1.0 Functional Description
1.1 Introduction
This document provides information about the NumonyxTM StrataFlash® Embedded
Memory (P33-65nm) device and describes its features, operations, and specifications.
P33-65nm is the latest generation of NumonyxTM StrataFlash® Embedded Memory
(P33-65nm) devices. P33-65nm device will be offered in 64-Mbit up through 2-Gbit
densities. This document covers specifically 256-Mbit and 512-Mbit (256M/256M)
product information. Benefits include more density in less space, high-speed interface
NOR device, and support for code and data storage. Features include high-performance
synchronous-burst read mode, fast asynchronous access times, low power, flexible
security options, and two industry-standard package choices.
P33-65nm is manufactured using Numonyx™ 65nm ETOX™ X process technology.
1.2 Overview
This family of devices provides high performance at low voltage on a 16-bit data bus.
Individually erasable memory blocks are sized for optimum code and data storage.
Upon initial power-up or return from reset, the device defaults to asynchronous page-
mode read. Configuring the RCR enables synchronous burst-mode reads. In
synchronous burst mode, output data is synchronized with a user-supplied clock signal.
A WAIT signal provides an easy CPU-to-flash memory synchronization.
In addition to the enhanced architecture and interface, the device incorporates
technology that enables fast factory program and erase operations. Designed for low-
voltage systems, the P33 Family Flash memory supports read operations with VCC at
3.0V, and erase and program operations with VPP at 3.0V or 9.0V. Buffered Enhanced
Factory Programming provides the fastest flash array programming performance with
VPP at 9.0V, which increases factory throughput. With VPP at 3.0V, VCC and VPP can be
tied together for a simple, ultra low power design. In addition to voltage flexibility, a
dedicated VPP connection provides complete data protection when VPP VPPLK.
The Command User Interface is the interface between the system processor and all
internal operations of the device. An internal Write State Machine automatically
executes the algorithms and timings necessary for block erase and program. A Status
Register indicates erase or program completion and any errors that may have occurred.
An industry-standard command sequence invokes program and erase automation. Each
erase operation erases one block. The Erase Suspend feature allows system software to
pause an erase cycle to read or program data in another block. Program Suspend
allows system software to pause programming to read other locations. Data is
programmed in word increments (16 bits).
The P33 Family Flash memory one-time-programmable (OTP) register allows unique
flash device identification that can be used to increase system security. The individual
Block Lock feature provides zero-latency block locking and unlocking. The P33-65nm
device adds enhanced protection via Password Access Mode which allows user to
protect write and/or read access to the defined blocks. In addition, the P33 Family
Flash memory may also provide the backward compatible OTP permanent lock feature.

1.3 Virtual Chip Enable Description
The 512 Mbit P33 Family Flash memory employs a Virtual Chip Enable which combines
two 256-Mbit die with a common chip enable, CE# for Easy BGA packages. Address
A25 is then used to select between the die pair with CE# asserted, depending upon the
package option used. When chip enable is asserted and A25 is low (VIL), The lower
parameter die is selected; when chip enable is asserted and A25 is high (VIH), the
upper parameter die is selected.

4.0 Signals
Table 4: TSOP and Easy BGA Signal Descriptions (Sheet 1 of 2)
Symbol Type Name and Function
A[MAX:1] Input
ADDRESS INPUTS: Device address inputs. 256-Mbit: A[24:1]; 512-Mbit: A[25:1]. Note: The
virtual selection of the 256-Mbit “Top parameter” die in the dual-die 512-Mbit configuration is
accomplished by setting A[25] high (VIH).
DQ[15:0] Input/
Output
DATA INPUT/OUTPUTS: Inputs data and commands during write cycles; outputs data during
reads of memory, status register, OTP register, and read configuration register. Data balls float when
the CE# or OE# are deasserted. Data is internally latched during writes.
ADV# Input
ADDRESS VALID: Active low input. During synchronous read operations, addresses are latched on
the rising edge of ADV#, or on the next valid CLK edge with ADV# low, whichever occurs first.
In asynchronous mode, the address is latched when ADV# going high or continuously flows through
if ADV# is held low.
WARNING: Designs not using ADV# must tie it to VSS to allow addresses to flow through.
CE# Input
CHIP ENABLE: Active low input. CE# low selects the associated flash memory die. When asserted,
flash internal control logic, input buffers, decoders, and sense amplifiers are active. When
deasserted, the associated flash die is deselected, power is reduced to standby levels, data and
WAIT outputs are placed in high-Z state.
WARNING: All chip enables must be high when device is not in use.
CLK Input
CLOCK: Synchronizes the device with the system’s bus frequency in synchronous-read mode.
During synchronous read operations, addresses are latched on the rising edge of ADV#, or on the
next valid CLK edge with ADV# low, whichever occurs first.
WARNING: Designs not using CLK for synchronous read mode must tie it to VCCQ or VSS.
OE# Input OUTPUT ENABLE: Active low input. OE# low enables the device’s output data buffers during read
cycles. OE# high places the data outputs and WAIT in High-Z.
RST# Input
RESET: Active low input. RST# resets internal automation and inhibits write operations. This
provides data protection during power transitions. RST# high enables normal operation. Exit from
reset places the device in asynchronous read array mode.
WAIT Output
WAIT: Indicates data valid in synchronous array or non-array burst reads. RCR[10], (WT)
determines its polarity when asserted. WAIT’s active output is VOL or VOH when CE# and OE# are
VIL. WAIT is high-Z if CE# or OE# is VIH.
In synchronous array or non-array read modes, WAIT indicates invalid data when asserted and
valid data when deasserted.
In asynchronous page mode, and all write modes, WAIT is deasserted.
WE# Input WRITE ENABLE: Active low input. WE# controls writes to the device. Address and data are latched
on the rising edge of WE#.
WP# Input
WRITE PROTECT: Active low input. WP# low enables the lock-down mechanism. Blocks in lock-
down cannot be unlocked with the Unlock command. WP# high overrides the lock-down function
enabling blocks to be erased or programmed using software commands.
VPP Power/
Input
ERASE AND PROGRAM POWER: A valid voltage on this pin allows erasing or programming.
Memory contents cannot be altered when VPP VPPLK. Block erase and program at invalid VPP
voltages should not be attempted.
Set VPP = VPPL for in-system program and erase operations. To accommodate resistor or diode drops
from the system supply, the VIH level of VPP can be as low as VPPL min. VPP must remain above VPPL
min to perform in-system flash modification. VPP may be 0 V during read operations.
VPPH can be applied to main blocks for 1000 cycles maximum and to parameter blocks for 2500
cycles. VPP can be connected to 9 V for a cumulative total not to exceed 80 hours. Extended use of
this pin at 9 V may reduce block cycling capability.
VCC Power DEVICE CORE POWER SUPPLY: Core (logic) source voltage. Writes to the flash array are inhibited
when VCC VLKO. Operations at invalid VCC voltages should not be attempted.
VCCQ Power OUTPUT POWER SUPPLY: Output-driver source voltage.
VSS Power GROUND: Connect to system ground. Do not float any VSS connection.

5.0 Bus Operations
CE# low and RST# high enable device read operations. The device internally decodes
upper address inputs to determine the accessed block. ADV# low opens the internal
address latches. OE# low activates the outputs and gates selected data onto the I/O
bus.
In asynchronous mode, the address is latched when ADV# goes high or continuously
flows through if ADV# is held low. In synchronous mode, the address is latched by the
first of either the rising ADV# edge or the next valid CLK edge with ADV# low (WE#
and RST# must be VIH; CE# must be VIL).
Bus cycles to/from the P33-65nm device conform to standard microprocessor bus
operations. Table 5, “Bus Operations Summary”summarizes the bus operations and the
logic levels that must be applied to the device control signal inputs.
5.1 Read
To perform a read operation, RST# and WE# must be deasserted while CE# and OE#
are asserted. CE# is the device-select control. When asserted, it enables the flash
memory device. OE# is the data-output control. When asserted, the addressed flash
memory data is driven onto the I/O bus.
5.2 Write
To perform a write operation, both CE# and WE# are asserted while RST# and OE# are
deasserted. During a write operation, address and data are latched on the rising edge
of WE# or CE#, whichever occurs first. Table 7, “Command Bus Cycles” on page 19
shows the bus cycle sequence for each of the supported device commands, while
Table 6, “Command Codes and Definitions” on page 17 describes each command. See
Section 15.0, “AC Characteristics” on page 48 for signal-timing details.
Note: Write operations with invalid VCC and/or VPP voltages can produce spurious results and
should not be attempted.
5.3 Output Disable
When OE# is deasserted, device outputs DQ[15:0] are disabled and placed in a high-
impedance (High-Z) state, WAIT is also placed in High-Z.

5.4 Standby
When CE# is deasserted the device is deselected and placed in standby, substantially
reducing power consumption. In standby, the data outputs are placed in High-Z,
independent of the level placed on OE#. Standby current, ICCS, is the average current
measured over any 5 ms time interval, 5 µs after CE# is deasserted. During standby,
average current is measured over the same time interval 5 µs after CE# is deasserted.
When the device is deselected (while CE# is deasserted) during a program or erase
operation, it continues to consume active power until the program or erase operation is
completed.
5.5 Reset
As with any automated device, it is important to assert RST# when the system is reset.
When the system comes out of reset, the system processor attempts to read from the
flash memory if it is the system boot device. If a CPU reset occurs with no flash
memory reset, improper CPU initialization may occur because the flash memory may
be providing status information rather than array data. Flash memory devices from
Numonyx allow proper CPU initialization following a system reset through the use of the
RST# input. RST# should be controlled by the same low-true reset signal that resets
the system CPU.
After initial power-up or reset, the device defaults to asynchronous Read Array mode,
and the Status Register is set to 0x80. Asserting RST# de-energizes all internal
circuits, and places the output drivers in High-Z. When RST# is asserted, the device
shuts down the operation in progress, a process which takes a minimum amount of
time to complete. When RST# has been deasserted, the device is reset to
asynchronous Read Array state.
Note: If RST# is asserted during a program or erase operation, the operation is terminated
and the memory contents at the aborted location (for a program) or block (for an
erase) are no longer valid, because the data may have been only partially written or
erased.
When returning from a reset (RST# deasserted), a minimum wait is required before the
initial read access outputs valid data. Also, a minimum delay is required after a reset
before a write cycle can be initiated. After this wake-up interval passes, normal
operation is restored. See Section 15.0, “AC Characteristics” on page 48 for details
about signal-timing.

6.0 Command Set
6.1 Device Command Codes
The system Central Processing Unit provides control of all in-system read, write, and
erase operations of the device via the system bus. The on-chip WSM manages all block-
erase and word-program algorithms.
Device commands are written to the CUI to control all flash memory device operations.
The CUI does not occupy an addressable memory location; it is the mechanism through
which the flash device is controlled. Ta b l e 6 shows valid device command codes and
descriptions.
Table 6: Command Codes and Definitions (Sheet 1 of 2)
Mode Code Device Mode Description
Read
0xFF Read Array Places the device in Read Array mode. Array data is output on DQ[15:0].
0x70 Read Status

The WSM can only set SR error bits. The Clear Status Register command is
used to clear the SR error bits.
Write
0x40 Word Program
Setup
First cycle of a 2-cycle programming command; prepares the CUI for a write
operation. On the next write cycle, the address and data are latched and the
WSM executes the programming algorithm at the addressed location. During
program operations, the device responds only to Read Status Register and
Program Suspend commands. CE# or OE# must be toggled to update the
Status Register in asynchronous read. CE# or ADV# must be toggled to
update the SR Data for synchronous Non-array reads. The Read Array
command must be issued to read array data after programming has finished.
0xE8 Buffered Program This command loads a variable number of words up to the buffer size of 512
words onto the program buffer.
0xD0 Buffered Program
Confirm
The confirm command is Issued after the data streaming for writing into the
buffer is done. This instructs the WSM to perform the Buffered Program
algorithm, writing the data from the buffer to the flash memory array.
0x80 BEFP Setup
First cycle of a 2-cycle command; initiates the BEFP mode. The CUI then
waits for the BEFP Confirm command, 0xD0, that initiates the BEFP
algorithm. All other commands are ignored when BEFP mode begins.
0xD0 BEFP Confirm If the previous command was BEFP Setup (0x80), the CUI latches the
address and data, and prepares the device for BEFP mode.
Erase
0x20 Block Erase Setup
First cycle of a 2-cycle command; prepares the CUI for a block-erase
operation. The WSM performs the erase algorithm on the block addressed by
the Erase Confirm command. If the next command is not the Erase Confirm
(0xD0) command, the CUI sets Status Register bits SR [5,4], and places the
device in Read Status Register mode.
0xD0 Block Erase Confirm
If the first command was Block Erase Setup (0x20), the CUI latches the
address and data, and the WSM erases the addressed block. During block-
erase operations, the device responds only to Read Status Register and Erase
Suspend commands. CE# or OE# must be toggled to update the Status
Register in asynchronous read. CE# or ADV# must be toggled to update the
SR Data for synchronous Non-array reads.

6.2 Device Command Bus Cycles
Device operations are initiated by writing specific device commands to the CUI. See
Table 7, “Command Bus Cycles” on page 19. Several commands are used to modify
array data including Word Program and Block Erase commands. Writing either
command to the CUI initiates a sequence of internally-timed functions that culminate in
the completion of the requested task. However, the operation can be aborted by either
asserting RST# or by issuing an appropriate suspend command.
Suspend
0xB0 Program or Erase
Suspend
This command issued to any device address initiates a suspend of the
currently-executing program or block erase operation. The Status Register
indicates successful suspend operation by setting either SR.2 (program
suspended) or SR 6 (erase suspended), along with SR.7 (ready). The WSM
remains in the suspend mode regardless of control signal states (except for
RST# asserted).
0xD0 Suspend Resume This command issued to any device address resumes the suspended program
or block-erase operation.
Protection
0x60 Block lock Setup
First cycle of a 2-cycle command; prepares the CUI for block lock
configuration changes. If the next command is not Block Lock (0x01), Block
Unlock (0xD0), or Block Lock-Down (0x2F), the CUI sets SR.5 and SR.4,
indicating a command sequence error.
0x01 Block lock If the previous command was Block Lock Setup (0x60), the addressed block
is locked.
0xD0 Unlock Block
If the previous command was Block Lock Setup (0x60), the addressed block
is unlocked. If the addressed block is in a lock-down state, the operation has
no effect.

7.0 Read Operation
The device can be in any of four read states: Read Array, Read Identifier, Read Status
or Read Query. Upon power-up, or after a reset, the device defaults to Read Array
mode. To change the read state, the appropriate read command must be written to the
device (see Section 6.2, “Device Command Bus Cycles” on page 18). The following
sections describe read-mode operations in detail.
The device supports two read modes: asynchronous page mode and synchronous burst
mode. Asynchronous page mode is the default read mode after device power-up or a
reset. The RCR must be configured to enable synchronous burst reads of the flash
memory array (see Section 11.1, “Read Configuration Register” on page 34).
7.1 Asynchronous Page-Mode Read
Following a device power-up or reset, asynchronous page mode is the default read
mode and the device is set to Read Array mode. However, to perform array reads after
any other device operation (e.g. write operation), the Read Array command must be
issued in order to read from the flash memory array.
Note: Asynchronous page-mode reads can only be performed when RCR.15 is set
The Clear Status Register command clears the status register. It functions independent
of VPP. The WSM sets and clears SR[7,6,2], but it sets bits SR[5,3,1] without clearing
them. The Status Register should be cleared before starting a command sequence to
avoid any ambiguity. A device reset also clears the Status Register.
To perform an asynchronous page-mode read, an address is driven onto the address
bus, and CE# and ADV# are asserted. WE# and RST# must already have been
deasserted. WAIT is deasserted during asynchronous page mode. ADV# can be driven
high to latch the address, or it must be held low throughout the read cycle. CLK is not
used for asynchronous page-mode reads, and is ignored. If only asynchronous reads
are to be performed, CLK should be tied to a valid VIH level, WAIT signal can be floated
and ADV# must be tied to ground. Array data is driven onto DQ[15:0] after an initial
access time tAVQV delay. (see Section 15.0, “AC Characteristics” on page 48).
In asynchronous page mode, sixteen data words are “sensed” simultaneously from the
flash memory array and loaded into an internal page buffer. The buffer word
corresponding to the initial address on the Address bus is driven onto DQ[15:0] after
the initial access delay. The lowest four address bits determine which word of the
16-word page is output from the data buffer at any given time.
7.2 Synchronous Burst-Mode Read
To perform a synchronous burst-read, an initial address is driven onto the address bus,
and CE# and ADV# are asserted. WE# and RST# must already have been deasserted.
ADV# is asserted, and then deasserted to latch the address. Alternately, ADV# can
remain asserted throughout the burst access, in which case the address is latched on
the next valid CLK edge while ADV# is asserted.
During synchronous array and non-array read modes, the first word is output from the
data buffer on the next valid CLK edge after the initial access latency delay (see Section
11.1.2, “Latency Count” on page 35). Subsequent data is output on valid CLK edges
following a minimum delay. However, for a synchronous non-array read, the same word
of data will be output on successive clock edges until the burst length requirements are
satisfied. Refer to the following waveforms for more detailed information:

The Read Device Identifier command instructs the device to output manufacturer code,

data (see Section 6.2, “Device Command Bus Cycles” on page 18 for details on issuing
the Read Device Identifier command). Table 8, “Device Identifier Information” on

8.0 Program Operation
The device supports three programming methods: Word Programming (40h or 10h),
Buffered Programming (E8h, D0h), and Buffered Enhanced Factory Programming (80h,
D0h). The following sections describe device programming in detail.
Successful programming requires the addressed block to be unlocked. If the block is
locked down, WP# must be deasserted and the block must be unlocked before
attempting to program the block. Attempting to program a locked block causes a
program error (SR.4 and SR.1 set) and termination of the operation. See Section 10.0,
“Security” on page 30 for details on locking and unlocking blocks.
8.1 Word Programming
Word programming operations are initiated by writing the Word Program Setup
command to the device. This is followed by a second write to the device with the
address and data to be programmed. The device outputs Status Register data when
read. See Figure 31, “Word Program Flowchart” on page 72. VPP must be above VPPLK,
and within the specified VPPL min/max values.
During programming, the WSM executes a sequence of internally-timed events that
program the desired data bits at the addressed location, and verifies that the bits are
sufficiently programmed. Programming the flash memory array changes “ones” to
“zeros”. Memory array bits that are zeros can be changed to ones only by erasing the
block.
The Status Register can be examined for programming progress and errors by reading
at any address. The device remains in the Read Status Register state until another
command is written to the device.
Status Register bit SR.7 indicates the programming status while the sequence
executes. Commands that can be issued to the device during programming are
Program Suspend, Read Status Register, Read Device Identifier, Read CFI, and Read
Array (this returns unknown data).
When programming has finished, Status Register bit SR.4 (when set) indicates a
programming failure. If SR.3 is set, the WSM could not perform the word programming
operation because VPP was outside of its acceptable limits. If SR.1 is set, the word
programming operation attempted to program a locked block, causing the operation to
abort.
Before issuing a new command, the Status Register contents should be examined and
then cleared using the Clear Status Register command. Any valid command can follow,
when word programming has completed.
8.2 Buffered Programming
The device features a 512-word buffer to enable optimum programming performance.
For Buffered Programming, data is first written to an on-chip write buffer. Then the
buffer data is programmed into the flash memory array in buffer-size increments. This
can improve system programming performance significantly over non-buffered
programming. (see Figure 33, “Buffer Program Flowchart” on page 74).
When the Buffered Programming Setup command is issued, Status Register information
is updated and reflects the availability of the buffer. SR.7 indicates buffer availability: if
set, the buffer is available; if cleared, the buffer is not available.
Note: The device default state is to output SR data after the Buffer Programming Setup
Command. CE# and OE# low drive device to update Status Register. It is not allowed
P33-65nm
Datasheet Aug 2009
24 Order Number: 320003-08
to issue 70h to read SR data after E8h command otherwise 70h would be counted as
Word Count.
On the next write, a word count is written to the device at the buffer address. This tells
the device how many data words will be written to the buffer, up to the maximum size
of the buffer.
On the next write, a device start address is given along with the first data to be written
to the flash memory array. Subsequent writes provide additional device addresses and
data. All data addresses must lie within the start address plus the word count.
Optimum programming performance and lower power usage are obtained by aligning
the starting address at the beginning of a 512-word boundary (A[9:1] = 0x00). The
maximum buffer size would be 256-word if the misaligned address range is crossing a
512-word boundary during programming.
After the last data is written to the buffer, the Buffered Programming Confirm command
must be issued to the original block address. The WSM begins to program buffer
contents to the flash memory array. If a command other than the Buffered
Programming Confirm command is written to the device, a command sequence error
occurs and SR[7,5,4] are set. If an error occurs while writing to the array, the device
stops programming, and SR[7,4] are set, indicating a programming failure.
When Buffered Programming has completed, additional buffer writes can be initiated by
issuing another Buffered Programming Setup command and repeating the buffered
program sequence. Buffered programming may be performed with VPP = VPPL or VPPH
(see Section 13.2, “Operating Conditions” on page 45 for limitations when operating
the device with VPP = VPPH).
If an attempt is made to program past an erase-block boundary using the Buffered
Program command, the device aborts the operation. This generates a command
sequence error, and SR[5,4] are set.
If Buffered programming is attempted while VPP is below VPPLK, SR[4,3] are set. If any
errors are detected that have set Status Register bits, the Status Register should be
cleared using the Clear Status Register command.
8.3 Buffered Enhanced Factory Programming
Buffered Enhanced Factory Programing (BEFP) speeds up Multi-Level Cell (MLC) flash
programming. The enhanced programming algorithm used in BEFP eliminates
traditional programming elements that drive up overhead in device programmer
systems. (see Figure 34, “BEFP Flowchart” on page 75).
BEFP consists of three phases: Setup, Program/Verify, and Exit It uses a write buffer to
spread MLC program performance across 512 data words. Verification occurs in the
same phase as programming to accurately program the flash memory cell to the
correct bit state.
A single two-cycle command sequence programs the entire block of data. This
enhancement eliminates three write cycles per buffer: two commands and the word
count for each set of 512 data words. Host programmer bus cycles fill the device’s write
buffer followed by a status check. SR.0 indicates when data from the buffer has been
programmed into sequential flash memory array locations.
Following the buffer-to-flash array programming sequence, the Write State Machine
(WSM) increments internal addressing to automatically select the next 512-word array
boundary. This aspect of BEFP saves host programming equipment the address-bus
setup overhead.

With adequate continuity testing, programming equipment can rely on the WSM’s
internal verification to ensure that the device has programmed properly. This eliminates
the external post-program verification and its associated overhead.
8.3.1 BEFP Requirements and Considerations
BEFP requirements:
Case temperature: TC = 30 °C ± 10 °C
•Nominal VCC
•VPP driven to V
PPH
Target block must be unlocked before issuing the BEFP Setup and Confirm
commands
The first-word address for the block to be programmed must be held constant from
the setup phase through all data streaming into the target block, until transition to
the exit phase is desired.
The first-word address must align with the start of an array buffer boundary. Word
buffer boundaries in the array are determined by A[8:0] (0x000 through 01FF); the
alignment start point is A[8:0] = 0x000.
BEFP considerations:
For optimum performance, cycling must be limited below 50 erase cycles per block.
Some degradation in performance may occur is this limit is exceeded, but the
internal algorithm continues to work properly.
BEFP programs one block at a time; all buffer data must fall within a single block. If
the internal address counter increments beyond the block’s maximum address,
addressing wraps around to the beginning of the block.
BEFP cannot be suspended
Programming to the flash memory array can occur only when the buffer is full. If
the number of words is less than 512, remaining locations must be filled with
0xFFFF.
8.3.2 BEFP Setup Phase
After receiving the BEFP Setup and Confirm command sequence, Status Register bit
SR.7 (Ready) is cleared, indicating that the WSM is busy with BEFP algorithm startup. A
delay before checking SR.7 is required to allow the WSM enough time to perform all of
its setups and checks (Block-Lock status, VPP level, etc.). If an error is detected, SR.4
is set and BEFP operation terminates. If the block was found to be locked, SR.1 is also
set. SR.3 is set if the error occurred due to an incorrect VPP level.
Note: Reading from the device after the BEFP Setup and Confirm command sequence outputs
Status Register data. Do not issue the Read Status Register command; it will be
interpreted as data to be loaded into the buffer.
8.3.3 BEFP Program/Verify Phase
After the BEFP Setup Phase has completed, the host programming system must check
SR[7,0] to determine the availability of the write buffer for data streaming. SR.7
cleared indicates the device is busy and the BEFP program/verify phase is activated.
SR.0 indicates the write buffer is available.
Two basic sequences repeat in this phase: loading of the write buffer, followed by buffer
data programming to the array. For BEFP, the count value for buffer loading is always
the maximum buffer size of 512 words. During the buffer-loading sequence, data is
P33-65nm
Datasheet Aug 2009
26 Order Number: 320003-08
stored to sequential buffer locations starting at address 0x00. Programming of the
buffer contents to the flash memory array starts as soon as the buffer is full. If the
number of words is less than 512, the remaining buffer locations must be filled with
0xFFFF.
Caution: The buffer must be completely filled for programming to occur. Supplying an
address outside of the current block's range during a buffer-fill sequence
causes the algorithm to exit immediately. Any data previously loaded into the
buffer during the fill cycle is not programmed into the array.
The starting address for data entry must be buffer size aligned, if not the BEFP
algorithm will be aborted and the program fails and (SR.4) flag will be set.
Data words from the write buffer are directed to sequential memory locations in the
flash memory array; programming continues from where the previous buffer sequence
ended. The host programming system must poll SR.0 to determine when the buffer
program sequence completes. SR.0 cleared indicates that all buffer data has been
transferred to the flash array; SR.0 set indicates that the buffer is not available yet for
the next fill cycle. The host system may check full status for errors at any time, but it is
only necessary on a block basis after BEFP exit. After the buffer fill cycle, no write
cycles should be issued to the device until SR.0 = 0 and the device is ready for the next
buffer fill.
Note: Any spurious writes are ignored after a buffer fill operation and when internal program
is proceeding.
The host programming system continues the BEFP algorithm by providing the next
group of data words to be written to the buffer. Alternatively, it can terminate this
phase by changing the block address to one outside of the current block’s range.
The Program/Verify phase concludes when the programmer writes to a different block
address; data supplied must be 0xFFFF. Upon Program/Verify phase completion, the
device enters the BEFP Exit phase.
8.3.4 BEFP Exit Phase
When SR.7 is set, the device has returned to normal operating conditions. A full status
check should be performed at this time to ensure the entire block programmed
successfully. When exiting the BEFP algorithm with a block address change, the read
mode will not change. After BEFP exit, any valid command can be issued to the device.
8.4 Program Suspend
Issuing the Program Suspend command while programming suspends the
programming operation. This allows data to be accessed from the device other than the
one being programmed. The Program Suspend command can be issued to any device
address. A program operation can be suspended to perform reads only. Additionally, a
program operation that is running during an erase suspend can be suspended to
perform a read operation (see Figure 32, “Program Suspend/Resume Flowchart” on
page 73).
When a programming operation is executing, issuing the Program Suspend command
requests the WSM to suspend the programming algorithm at predetermined points. The
device continues to output Status Register data after the Program Suspend command is
issued. Programming is suspended when Status Register bits SR[7,2] are set. Suspend
latency is specified in Section 15.5, “Program and Erase Characteristics” on page 58.
Datasheet Aug 2009
27 Order Number:320003-08
P33-65nm
To read data from the device, the Read Array command must be issued. Read Array,
Read Status Register, Read Device Identifier, Read CFI, and Program Resume are valid
commands during a program suspend.
During a program suspend, deasserting CE# places the device in standby, reducing
active current. VPP must remain at its programming level, and WP# must remain
unchanged while in program suspend. If RST# is asserted, the device is reset.
8.5 Program Resume
The Resume command instructs the device to continue programming, and
automatically clears Status Register bits SR[7,2]. This command can be written to any
address. If error bits are set, the Status Register should be cleared before issuing the
next instruction. RST# must remain deasserted (see Figure 32, “Program Suspend/
Resume Flowchart” on page 73).
8.6 Program Protection
When VPP = VIL, absolute hardware write protection is provided for all device blocks. If
VPP is at or below VPPLK, programming operations halt and SR.3 is set indicating a VPP-
level error. Block lock registers are not affected by the voltage level on VPP; they may
still be programmed and read, even if VPP is less than VPPLK.

9.0 Erase Operation
Flash erasing is performed on a block basis. An entire block is erased each time an
erase command sequence is issued, and only one block is erased at a time. When a
block is erased, all bits within that block read as logical ones. The following sections
describe block erase operations in detail.
9.1 Block Erase
Block erase operations are initiated by writing the Block Erase Setup command to the
address of the block to be erased (see Section 6.2, “Device Command Bus Cycles” on
page 18). Next, the Block Erase Confirm command is written to the address of the
block to be erased. If the device is placed in standby (CE# deasserted) during an erase
operation, the device completes the erase operation before entering standby. VPP must
be above VPPLK and the block must be unlocked (see Figure 35, “Block Erase Flowchart”
on page 76).
During a block erase, the WSM executes a sequence of internally-timed events that
conditions, erases, and verifies all bits within the block. Erasing the flash memory array
changes “zeros” to “ones”. Memory array bits that are ones can be changed to zeros
only by programming the block.
The Status Register can be examined for block erase progress and errors by reading
any address. The device remains in the Read Status Register state until another
command is written. SR.0 indicates whether the addressed block is erasing. Status
Register bit SR.7 is set upon erase completion.
Status Register bit SR.7 indicates block erase status while the sequence executes.
When the erase operation has finished, Status Register bit SR.5 indicates an erase
failure if set. SR.3 set would indicate that the WSM could not perform the erase
operation because VPP was outside of its acceptable limits. SR.1 set indicates that the
erase operation attempted to erase a locked block, causing the operation to abort.
Before issuing a new command, the Status Register contents should be examined and
then cleared using the Clear Status Register command. Any valid command can follow
once the block erase operation has completed.
9.2 Blank Check
The Blank Check operation determines whether a specified main block is blank (i.e.
completely erased). Without Blank Check, Block Erase would be the only other way to
ensure a block is completely erased. so Blank Check can be used to determine whether
or not a prior erase operation was successful; this includes erase operations that may
have been interrupted by power loss.
Blank check can apply to only one block at a time, and no operations other than Status
Register Reads are allowed during Blank Check (e.g. reading array data, program,
erase etc). Suspend and resume operations are not supported during Blank Check, nor
is Blank Check supported during any suspended operations.
Blank Check operations are initiated by writing the Blank Check Setup command to the
block address. Next, the Check Confirm command is issued along with the same block
address. When a successful command sequence is entered, the device automatically
enters the Read Status State. The WSM then reads the entire specified block, and
determines whether any bit in the block is programmed or over-erased.
Datasheet Aug 2009
29 Order Number:320003-08
P33-65nm
The status register can be examined for Blank Check progress and errors by reading
any address within the block being accessed. During a blank check operation, the
Status Register indicates a busy status (SR7 = 0). Upon completion, the Status
Register indicates a ready status (SR7 = 1). The Status Register should be checked for
any errors, and then cleared. If the Blank Check operation fails, which means the block
is not completely erased, the Status
9.3 Erase Suspend
Issuing the Erase Suspend command while erasing suspends the block erase operation.
This allows data to be accessed from memory locations other than the one being
erased. The Erase Suspend command can be issued to any device address. A block
erase operation can be suspended to perform a word or buffer program operation, or a
read operation within any block except the block that is erase suspended (see
Figure 37, “Erase Suspend/Resume Flowchart” on page 78).
When a block erase operation is executing, issuing the Erase Suspend command
requests the WSM to suspend the erase algorithm at predetermined points. The device
continues to output Status Register data after the Erase Suspend command is issued.
Block erase is suspended when Status Register bits SR[7,6] are set. Suspend latency is
specified in Section 15.5, “Program and Erase Characteristics” on page 58.
To read data from the device (other than an erase-suspended block), the Read Array
command must be issued. During Erase Suspend, a Program command can be issued
to any block other than the erase-suspended block. Block erase cannot resume until
program operations initiated during erase suspend complete. Read Array, Read Status
Register, Read Device Identifier, Read CFI, and Erase Resume are valid commands
during Erase Suspend. Additionally, Clear Status Register, Program, Program Suspend,
Block Lock, Block Unlock, and Block Lock-Down are valid commands during Erase
Suspend.
During an erase suspend, deasserting CE# places the device in standby, reducing
active current. VPP must remain at a valid level, and WP# must remain unchanged
while in erase suspend. If RST# is asserted, the device is reset.
9.4 Erase Resume
The Erase Resume command instructs the device to continue erasing, and
automatically clears SR[7,6]. This command can be written to any address. If status
register error bits are set, the Status Register should be cleared before issuing the next
instruction. RST# must remain deasserted.
9.5 Erase Protection
When VPP = VIL, absolute hardware erase protection is provided for all device blocks. If
VPP is at or below VPPLK, erase operations halt and SR.3 is set indicating a VPP-level
error.

10.0 Security
The device features security modes used to protect the information stored in the flash
memory array. The following sections describe each security mode in detail.
10.1 Block Locking
Individual instant block locking is used to protect user code and/or data within the flash
memory array. All blocks power up in a locked state to protect array data from being
altered during power transitions. Any block can be locked or unlocked with no latency.
Locked blocks cannot be programmed or erased; they can only be read.
Software-controlled security is implemented using the Block Lock and Block Unlock
commands. Hardware-controlled security can be implemented using the Block Lock-
Down command along with asserting WP#. Also, VPP data security can be used to
inhibit program and erase operations (see Section 8.6, “Program Protection” on
page 27 and Section 9.5, “Erase Protection” on page 29).
The P33-65nm device also offers four pre-defined areas in the main array that can be
configured as One-Time Programmable (OTP) for the highest level of security. These
include the four 32 KB parameter blocks together as one and the three adjacent 128 KB
main blocks. This is available for top or bottom parameter devices.
10.1.1 Lock Block
To lock a block, issue the Lock Block Setup command. The next command must be the
Lock Block command issued to the desired block’s address (see Section 6.2, “Device
Command Bus Cycles” on page 18 and Figure 36, “Block Lock Operations Flowchart” on
page 77). If the Set Read Configuration Register command is issued after the Block
Lock Setup command, the device configures the RCR instead.
Block lock and unlock operations are not affected by the voltage level on VPP. The block
lock bits may be modified and/or read even if VPP is at or below VPPLK.
10.1.2 Unlock Block
The Unlock Block command is used to unlock blocks (see Section 6.2, “Device
Command Bus Cycles” on page 18). Unlocked blocks can be read, programmed, and
erased. Unlocked blocks return to a locked state when the device is reset or powered
down. If a block is in a lock-down state, WP# must be deasserted before it can be
unlocked (see Figure 8, “Block Locking State Diagram” on page 31).
10.1.3 Lock-Down Block
A locked or unlocked block can be locked-down by writing the Lock-Down Block
command sequence (see Section 6.2, “Device Command Bus Cycles” on page 18).
Blocks in a lock-down state cannot be programmed or erased; they can only be read.
However, unlike locked blocks, their locked state cannot be changed by software
commands alone. A locked-down block can only be unlocked by issuing the Unlock
Block command with WP# deasserted. To return an unlocked block to locked-down
state, a Lock-Down command must be issued prior to changing WP# to VIL. Locked-
down blocks revert to the locked state upon reset or power up the device (see Figure 8,
“Block Locking State Diagram” on page 31).

P33-65nm
10.1.4 Block Lock Status
The Read Device Identifier command is used to determine a block’s lock status (see
Section 7.3, “Read Device Identifier” on page 22). Data bits DQ[1:0] display the
addressed block’s lock status; DQ0 is the addressed block’s lock bit, while DQ1 is the
addressed block’s lock-down bit.
Note: LK: Lock Setup Command, 60h; LK/D0h: Unlock Command; LK/01h: Lock Command; LK/2Fh: Lock-Down Command.
10.1.5 Block Locking During Suspend
Block lock and unlock changes can be performed during an erase suspend. To change
block locking during an erase operation, first issue the Erase Suspend command.
Monitor the Status Register until SR.7 and SR.6 are set, indicating the device is
suspended and ready to accept another command.
Next, write the desired lock command sequence to a block, which changes the lock
state of that block. After completing block lock or unlock operations, resume the erase
operation using the Erase Resume command.
Note: A Lock Block Setup command followed by any command other than Lock Block, Unlock
Block, or Lock-Down Block produces a command sequence error and set Status
Register bits SR.4 and SR.5. If a command sequence error occurs during an erase
suspend, SR.4 and SR.5 remains set, even after the erase operation is resumed. Unless
the Status Register is cleared using the Clear Status Register command before
resuming the erase operation, possible erase errors may be masked by the command
sequence error.

If a block is locked or locked-down during an erase suspend of the same block, the lock
status bits change immediately. However, the erase operation completes when it is
resumed. Block lock operations cannot occur during a program suspend. See Appendix
A, “Write State Machine” on page 81, which shows valid commands during an erase
suspend.
10.2 Selectable OTP Blocks
Blocks from the main array may be optionally configured as OTP. Ask your local
Numonyx representative for details about any of these selectable OTP implementations.
10.3 Password Access
Password Access is a security enhancement offered on the P33-65nm device.This
feature protects information stored in main-array memory blocks by preventing content
alteration or reads until a valid 64-bit password is received. Password Access may be
combined with Non-Volatile Protection and/or Volatile Protection to create a multi-
tiered solution. Please contact your Numonyx Sales for further details concerning
Password Access.

11.0 Status Register
To read the Status Register, issue the Read Status Register command at any address.
Status Register information is available to which the Read Status Register, Word
Program, or Block Erase command was issued. SRD is automatically made available
following a Word Program, Block Erase, or Block Lock command sequence. Reads from
the device after any of these command sequences outputs the device’s status until
another valid command is written (e.g. the Read Array command).
The Status Register is read using single asynchronous-mode or synchronous burst
mode reads. SRD is output on DQ[7:0], while 0x00 is output on DQ[15:8]. In
asynchronous mode the falling edge of OE#, or CE# (whichever occurs first) updates
and latches the Status Register contents. However, when reading the Status Register in
synchronous burst mode, CE# or ADV# must be toggled to update SRD.
The Device Write Status bit (SR.7) provides overall status of the device. SR[6:1]
present status and error information about the program, erase, suspend, VPP, and
block-locked operations.
Notes:
1. Always clear the Status Register prior to resuming erase operations. It avoids Status Register ambiguity when issuing
commands during Erase Suspend. If a command sequence error occurs during an erase-suspend state, the Status Register
contains the command sequence error status (SR[7,5,4] set). When the erase operation resumes and finishes, possible
errors during the erase operation cannot be detected via the Status Register because it contains the previous error status
2. BEFP mode is only valid in main array.

11.0.1 Clear Status Register
The Clear Status Register command clears the status register. It functions independent
of VPP. The WSM sets and clears SR[7,6,2], but it sets bits SR[5:3,1] without clearing
them. The Status Register should be cleared before starting a command sequence to
avoid any ambiguity. A device reset also clears the Status Register.
11.1 Read Configuration Register
The RCR is used to select the read mode (synchronous or asynchronous), and it defines
the synchronous burst characteristics of the device. To modify RCR settings, use the
Configure Read Configuration Register command (see Section 6.2, “Device Command
Bus Cycles” on page 18).
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see Section 7.3, “Read Device Identifier” on page 22).
The RCR is shown in Tab l e 1 1 . The following sections describe each RCR bit.

The Read Mode (RM) bit selects synchronous burst-mode or asynchronous page-mode
operation for the device. When the RM bit is set, asynchronous page mode is selected

11.1.2 Latency Count
The Latency Count (LC) bits tell the device how many clock cycles must elapse from the
rising edge of ADV# (or from the first valid clock edge after ADV# is asserted) until the
first valid data word is driven onto DQ[15:0]. The input clock frequency is used to
determine this value and Figure 9 shows the data output latency for the different
settings of LC. The maximum Latency Count for P33 would be Code 4 based on the Max
clock frequency specification of 52 MHz, and there will be zero WAIT States when
bursting within the word line. Please also refer to Section 11.1.3, “End of Word Line

Table 13: End of Wordline Data and WAIT state Comparison
11.1.4 WAIT Polarity
The WAIT Polarity bit (WP), RCR.10 determines the asserted level (VOH or VOL) of WAIT.
When WP is set, WAIT is asserted high. When WP is cleared, WAIT is asserted low
(default). WAIT changes state on valid clock edges during active bus cycles (CE#
asserted, OE# asserted, RST# deasserted).
11.1.5 WAIT Signal Function
The WAIT signal indicates data valid when the device is operating in synchronous mode
(RCR.15=0). The WAIT signal is only “deasserted” when data is valid on the bus.
When the device is operating in synchronous non-array read mode, such as read
status, read ID, or read query. The WAIT signal is also “deasserted” when data is valid
on the bus.
WAIT behavior during synchronous non-array reads at the end of word line works
correctly only on the first data access.
When the device is operating in asynchronous page mode, asynchronous single word
read mode, and all write operations, WAIT is set to a deasserted state as determined
by RCR.10. See Figure 18, “Asynchronous Single-Word Read (ADV# Latch)” on
page 52, and Figure 19, “Asynchronous Page-Mode Read Timing” on page 52.

11.1.6 WAIT Delay
The WAIT Delay (WD) bit controls the WAIT assertion-delay behavior during
synchronous burst reads. WAIT can be asserted either during or one data cycle before
valid data is output on DQ[15:0]. When WD is set, WAIT is deasserted one data cycle
before valid data (default). When WD is cleared, WAIT is deasserted during valid data.
11.1.7 Burst Sequence
The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst
sequence is supported. Table 1 5 shows the synchronous burst sequence for all burst
lengths, as well as the effect of the Burst Wrap (BW) setting.
Table 14: WAIT Functionality Table

All Asynchronous Reads Deasserted 1
All Writes High-Z 1,2
Notes:
1. Active: WAIT is asserted until data becomes valid, then deasserts.
2. When OE# = VIH during writes, WAIT = High-Z.

11.1.8 Clock Edge
The Clock Edge (CE) bit selects either a rising (default) or falling clock edge for CLK.
This clock edge is used at the start of a burst cycle, to output synchronous data, and to
assert/deassert WAIT.
11.1.9 Burst Wrap
The Burst Wrap (BW) bit determines whether 4, 8, or 16-word burst length accesses
wrap within the selected word-length boundaries or cross word-length boundaries.
When BW is set, burst wrapping does not occur (default). When BW is cleared, burst
wrapping occurs.
11.1.10 Burst Length
The Burst Length bits (BL[2:0]) selects the linear burst length for all synchronous burst
reads of the flash memory array. The burst lengths are 4-word, 8-word, 16-word, and
continuous word.
Continuous burst accesses are linear only, and do not wrap within any word length
boundaries (see Table 15, “Burst Sequence Word Ordering” on page 39). When a burst
cycle begins, the device outputs synchronous burst data until it reaches the end of the
“burstable” address space.
11.2 One-Time Programmable (OTP) Registers
The device contains 17 one-time programmable (OTP) registers that can be used to
implement system security measures and/or device identification. Each OTP register
can be individually locked.
The first 128-bit OTP Register is comprised of two 64-bit (8-word) segments. The lower
64-bit segment is pre-programmed at the Numonyx factory with a unique 64-bit
number. The other 64-bit segment, as well as the other sixteen 128-bit OTP Registers,
are blank. Users can program these registers as needed. Once programmed, users can
then lock the OTP Register(s) to prevent additional bit programming (see Figure 12,
“OTP Register Map” on page 41).

P33-65nm
The OTP Registers contain OTP bits; when programmed, PR bits cannot be erased. Each
OTP Register can be accessed multiple times to program individual bits, as long as the
register remains unlocked.
Each OTP Register has an associated Lock Register bit. When a Lock Register bit is
programmed, the associated OTP Register can only be read; it can no longer be
programmed. Additionally, because the Lock Register bits themselves are OTP, when
programmed, Lock Register bits cannot be erased. Therefore, when a OTP Register is
locked, it cannot be unlocked.
.
11.2.1 Reading the OTP Registers
The OTP Registers can be read from any address. To read the OTP Register, first issue
the Read Device Identifier command at any address to place the device in the Read
Device Identifier state (see Section 6.2, “Device Command Bus Cycles” on page 18).
Next, perform a read operation using the address offset corresponding to the register
to be read. Table 8, “Device Identifier Information” on page 22 shows the address
offsets of the OTP Registers and Lock Registers. PR data is read 16 bits at a time.

11.2.2 Programming the OTP Registers
To program any of the OTP Registers, first issue the Program OTP Register command at
the parameter’s base address plus the offset to the desired OTP Register (see Section
6.2, “Device Command Bus Cycles” on page 18). Next, write the desired OTP Register
data to the same OTP Register address (see Figure 12, “OTP Register Map” on
page 41).
The device programs the 64-bit and 128-bit user-programmable OTP Register data 16
bits at a time (see Figure 38, “OTP Register Programming Flowchart” on page 79).
Issuing the Program OTP Register command outside of the OTP Register’s address
space causes a program error (SR.4 set). Attempting to program a locked OTP Register
causes a program error (SR.4 set) and a lock error (SR.1 set).
Note: When programming the OTP bits in the OTP registers for a Top Parameter Device,
the following upper address bits must also be driven properly: A[Max:17] driven high
(VIH).
11.2.3 Locking the OTP Registers
Each OTP Register can be locked by programming its respective lock bit in the Lock
Register. To lock a OTP Register, program the corresponding bit in the Lock Register by
issuing the Program Lock Register command, followed by the desired Lock Register
data (see Section 6.2, “Device Command Bus Cycles” on page 18). The physical
addresses of the Lock Registers are 0x80 for register 0 and 0x89 for register 1. These
addresses are used when programming the lock registers (see Table 8, “Device
Identifier Information” on page 22).
Bit 0 of Lock Register 0 is already programmed during the manufacturing process at the
“factory”, locking the lower, pre-programmed 64-bit region of the first 128-bit OTP
Register containing the unique identification number of the device. Bit 1 of Lock
Register 0 can be programmed by the user to lock the user-programmable, 64-bit
region of the first 128-bit OTP Register. When programming Bit 1 of Lock Register 0, all
other bits need to be left as ‘1’ such that the data programmed is 0xFFFD.
Lock Register 1 controls the locking of the upper sixteen 128-bit OTP Registers. Each of
the 16 bits of Lock Register 1 correspond to each of the upper sixteen 128-bit OTP
Registers. Programming a bit in Lock Register 1 locks the corresponding 128-bit OTP
Register.
Caution: After being locked, the OTP Registers cannot be unlocked.

12.0 Power and Reset Specifications
12.1 Power-Up and Power-Down
Power supply sequencing is not required if VPP is connected to VCC or VCCQ. Otherwise
VCC and VCCQ should attain their minimum operating voltage before applying VPP.
Power supply transitions should only occur when RST# is low. This protects the device
from accidental programming or erasure during power transitions.
12.2 Reset Specifications
Asserting RST# during a system reset is important with automated program/erase
devices because systems typically expect to read from flash memory when coming out
of reset. If a CPU reset occurs without a flash memory reset, proper CPU initialization
may not occur. This is because the flash memory may be providing status information,
instead of array data as expected. Connect RST# to the same active low reset signal
used for CPU initialization.
Also, because the device is disabled when RST# is asserted, it ignores its control inputs
during power-up/down. Invalid bus conditions are masked, providing a level of memory
protection.

Notes:
1. These specifications are valid for all device versions (packages and speeds).
2. The device may reset if tPLPH is < tPLPH Min, but this is not guaranteed.
3. Not applicable if RST# is tied to VCC.
4. Sampled, but not 100% tested.
5. When RST# is tied to the VCC supply, device will not be ready until tVCCPH after VCC VCCMIN.
6. When RST# is tied to the VCCQ supply, device will not be ready until tVCCPH after VCC VCCMIN.
7. Reset completes within tPLPH if RST# is asserted while no erase or program operation is executing.

12.3 Power Supply Decoupling
Flash memory devices require careful power supply de-coupling. Three basic power
supply current considerations are: 1) standby current levels; 2) active current levels;
and 3) transient peaks produced when CE# and OE# are asserted and deasserted.
When the device is accessed, many internal conditions change. Circuits within the
device enable charge-pumps, and internal logic states change at high speed. All of
these internal activities produce transient signals. Transient current magnitudes depend
on the device outputs’ capacitive and inductive loading. Two-line control and correct
de-coupling capacitor selection suppress transient voltage peaks.
Because Numonyx MLC flash memory devices draw their power from VCC, VPP, and
VCCQ, each power connection should have a 0.1 µF ceramic capacitor to ground. High-
frequency, inherently low-inductance capacitors should be placed as close as possible
to package leads.
Additionally, for every eight devices used in the system, a 4.7 µF electrolytic capacitor
should be placed between power and ground close to the devices. The bulk capacitor is
meant to overcome voltage droop caused by PCB trace inductance.

Notes:
1. WAIT is driven per OE# assertion during synchronous array or non-array read, and can be configured to assert either
during or one data cycle before valid data.
2. This diagram illustrates the case in which an n-word burst is initiated to the flash memory array and it is terminated by
CE# deassertion after the first word in the burst.
Notes:
1. WAIT is driven per OE# assertion during synchronous array or non-array read, and can be configured to assert either
during or one data cycle before valid data.
2. At the end of Word Line; the delay incurred when a burst access crosses a 16-word boundary and the starting address is
not 4-word boundary aligned. See Section 11.1.3, “End of Word Line (EOWL) Considerations” on

Notes:
1. Write timing characteristics during erase suspend are the same as write-only operations.
2. A write operation can be terminated with either CE# or WE#.
3. Sampled, not 100% tested.
4. Write pulse width low (tWLWH or tELEH) is defined from CE# or WE# low (whichever occurs last) to CE# or WE# high
(whichever occurs first). Hence, tWLWH = tELEH = tWLEH = tELWH.
5. Write pulse width high (tWHWL or tEHEL) is defined from CE# or WE# high (whichever occurs first) to CE# or WE# low
(whichever occurs last). Hence, tWHWL = tEHEL = tWHEL = tEHWL).
6. tWHVH or tWHCH/L must be met when transiting from a write cycle to a synchronous burst read.
7. VPP and WP# should be at a valid level until erase or program success is determined.
8. This specification is only applicable when transiting from a write cycle to an asynchronous read. See spec W19 and W20
for synchronous read.
9. When doing a Read Status operation following any command that alters the Status Register, W14 is 20 ns.
10. Add 10 ns if the write operations results in a RCR or block lock status change, for the subsequent read operation to
reflect this change.
11. These specs are required only when the device is in a synchronous mode and clock is active during address setup phase.

Appendix A Supplemental Reference Information
A.1 Common Flash Interface
The Common Flash Interface (CFI) is part of an overall specification for multiple
command-set and control-interface descriptions. This appendix describes the database
structure containing the data returned by a read operation after issuing the Read CFI
command (see Section 6.2, “Device Command Bus Cycles” on page 18). System
software can parse this database structure to obtain information about the flash device,
such as block size, density, bus width, and electrical specifications. The system
software will then know which command set(s) to use to properly perform flash writes,
block erases, reads and otherwise control the flash device.
A.1.1 Query Structure Output
The Query database allows system software to obtain information for controlling the
flash device. This section describes the device’s CFI-compliant interface that allows
access to Query data.
Query data are presented on the lowest-order data outputs (DQ7-0) only. The numerical
offset value is the address relative to the maximum bus width supported by the device.
On this family of devices, the Query table device starting address is a 10h, which is a
word address for x16 devices.
For a word-wide (x16) device, the first two Query-structure bytes, ASCII “Q” and “R,
appear on the low byte at word addresses 10h and 11h. This CFI-compliant device
outputs 00h data on upper bytes. The device outputs ASCII “Q” in the low byte (DQ7-0)
and 00h in the high byte (DQ15-8).
At Query addresses containing two or more bytes of information, the least significant
data byte is presented at the lower address, and the most significant data byte is
presented at the higher address.
In all of the following tables, addresses and data are represented in hexadecimal
notation, so the “h” suffix has been dropped. In addition, since the upper byte of word-
wide devices is always “00h,” the leading “00” has been dropped from the table
notation and only the lower byte value is shown. Any x16 device outputs have 00h on
the upper byte in this mode.

Table 29: Example of Query Structure Output of x16 Devices
A.1.2 Query Structure Overview
The Query command causes the flash component to display the Common Flash Interface (CFI)
Query structure or database. Table 30 summarizes the structure sub-sections and address
locations.
Table 30: Query Structure
Note:
1. Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a function of
device bus width and mode.
2. BA = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32-KWord).
3. Offset 15 defines “P” which points to the Primary Numonyx-specific Extended Query Table.
A.1.3 Read CFI Identification String
The Identification String provides verification that the component supports the
Common Flash Interface specification. It also indicates the specification version and
supported vendor-specified command set(s).

register. Count ranges for this device are N =0000h to 00FFh.
2. The device outputs the status register when read.
3. Write Buffer contents will be programmed at the device start
address or destination flash address .
4. Align the start address on a Write Buffer boundary for maximum
programming performance (i.e., A
8
-A
1
of the start address =0).
5. The device aborts the Buffered Program command if the
current address is outside the original block address .
6. The Status register indicates an “improper command
Sequence” if the Buffered Program command is aborted. Follow
this with a Clear Status Register command .
7. The device default state is to output SR data after the Buffered
Programming Setup Command (E8h).CE# and OE low drive the
device to update Status Register . It is not allowed to issue 70h to
read SR data after E8h command otherwise 70h would be
counted as Word count.
8. Full status check can be done after all erase and write
sequences complete . Write FFh after the last operation to reset
the device to read array mode.

A.3 Write State Machine
Show here are the command state transitions (Next State Table) based on incoming
commands. Only one partition can be actively programming or erasing at a time. Each
partition stays in its last read state (Read Array, Read Device ID, Read CFI or Read
Status Register) until a new command changes it. The next WSM state does not depend
on the partition’s output state.
Note: IS refers to Illegal State in the Next State Tables.

Notes:
1. IS refers to Illegal State in the Next State Table.
2. “Illegal commands” include commands outside of the allowed command set.
3. The device defaults to "Read Array" on powerup.
4. If a “Read Array” is attempted when the device is busy, the result will be “garbage” data (we should not tell the user that
it will actually be Status Register data). The key point is that the output mux will be pointing to the “array”, but garbage
data will be output. “Read ID” and "Read Query" commands do the exact same thing in the device. The ID and Query data
are located at different locations in the address map.
5. The Clear Status command only clears the error bits in the status register if the device is not in the following modes:1.
WSM running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP modes) 2. Suspend states (Erase
Suspend, Pgm Suspend, Pgm Suspend In Erase Suspend).
6. BEFP writes are only allowed when the status register bit #0 = 0 or else the data is ignored.
7. Confirm commands (Lock Block, Unlock Block, Lock-Down Block, Configuration Register and Blank Check) perform the
operation and then move to the Ready State.
8. Buffered programming will botch when a different block address (as compared to the address given on the first data write
cycle) is written during the BP Load1 and BP Load2 states.
9. All two cycle commands will be considered as a contiguous whole during device suspend states. Individual commands will
not be parsed separately. (I.e. If an erase set-up command is issued followed by a D0h command, the D0h command will
not resume the program operation. Issuing the erase set-up places the CUI in an “illegal state”. A subsequent command
will clear the “illegal state”, but the command will be otherwise ignored.
