Product Description
The SST39WF800B is a 512K x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST proprie-
tary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tun-
neling injector attain better reliability and manufacturability compared to alternate approaches. The
SST39WF800B writes (Program or Erase) with a 1.65-1.95V power supply. This device conforms to
JEDEC standard pin assignments for x16 memories.
The SST39WF800B features high-performance Word-Programming which provides a typical Word-
Program time of 28 µsec. It uses Toggle Bit or Data# Polling to detect the completion of the Program or
Erase operation. On-chip hardware and software data protection schemes protects against inadvertent
writes. Designed, manufactured, and tested for a wide spectrum of applications, the SST39WF800B is
offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than
100 years.
The SST39WF800B is suited for applications that require convenient and economical updating of pro-
gram, configuration, or data memory. It significantly improves performance and reliability of all system
applications while lowering power consumption. It inherently uses less energy during Erase and Pro-
gram than alternative flash technologies. When programming a flash device, the total energy con-
sumed is a function of the applied voltage, current, and time of application. For any given voltage
range, SuperFlash technology uses less current to program and has a shorter erase time; therefore,
the total energy consumed during any Erase or Program operation is less than alternative flash tech-
nologies. These devices also improve flexibility while lowering the cost for program, data, and configu-
ration storage applications.
SuperFlash technology provides fixed Erase and Program times independent of the number of Erase/
Program cycles that have occurred. Consequently, the system software or hardware does not have to
be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Program
times increase with accumulated Erase/Program cycles.
To meet surface mount requirements, the SST39WF800B is offered in 48-ball TFBGA, 48-ball
WFBGA, and a 48-ball XFLGA packages. See Figures 2 and 3 for pin assignments and Table 1 for pin
descriptions.

Device Operation
Commands, which are used to initiate the memory operation functions of the device, are written to the
device using standard microprocessor write sequences. A command is written by asserting WE# low
while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever
occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first.
Read
The Read operation of the SST39WF800B is controlled by CE# and OE#; both have to be low for the
system to obtain data from the outputs.
CE# is used for device selection. When CE# is high, the chip is deselected and only standby power is
consumed.
OE# is the output control and is used to gate data from the output pins. The data bus is in high imped-
ance state when either CE# or OE# is high. See Figure 5.
Word-Program Operation
The SST39WF800B is programmed on a word-by-word basis. The sector where the word exists must
be fully erased before programming.
Programming is accomplished in three steps:
1. Load the three-byte sequence for Software Data Protection.
2. Load word address and word data. During the Word-Program operation, the addresses
are latched on the falling edge of either CE# or WE#, whichever occurs last. The data is
latched on the rising edge of either CE# or WE#, whichever occurs first.
3. Initiate the internal Program operation after the rising edge of the fourth WE# or CE#,
whichever occurs first. Once initiated, the Program operation will be completed within 40
µs. See Figures 6 and 7 for WE# and CE# controlled Program operation timing diagrams
and Figure 17 for flowcharts.
During the Program operation, the only valid reads are Data# Polling and Toggle Bit. During the inter-
nal Program operation, the host is free to perform additional tasks. Any commands issued during the
internal Program operation are ignored.

Sector-/Block-Erase Operation
The SST39WF800B offers both Sector-Erase and Block-Erase modes which allow the system to erase
the device on a sector-by-sector, or block-by-block, basis.
The sector architecture is based on uniform sector size of 2 KWord. Initiate the Sector-Erase operation
by executing a six-byte command sequence with Sector-Erase command (30H) and sector address
(SA) in the last bus cycle.
The Block-Erase mode is based on uniform block size of 32 KWord. Initiate the Block-Erase operation
by executing a six-byte command sequence with Block-Erase command (50H) and block address (BA)
in the last bus cycle.
The sector or block address is latched on the falling edge of the sixth WE# pulse, while the command
(30H or 50H) is latched on the rising edge of the sixth WE# pulse. The internal Erase operation begins
after the sixth WE# pulse.
The End-of-Erase operation can be determined using either Data# Polling or Toggle Bit methods. See
Figures 10 and 11 for timing waveforms. Any commands issued during the Sector- or Block-Erase
operation are ignored.
Chip-Erase Operation
The SST39WF800B provides a Chip-Erase operation, which allows the user to erase the entire mem-
ory array to the ‘1’ state. This is useful when the entire device must be quickly erased.
Initiate the Chip-Erase operation by executing a six-byte command sequence with Chip-Erase com-
mand (10H) at address 5555H in the last byte sequence.
The Erase operation begins with the rising edge of the sixth WE# or CE#, whichever occurs first. Dur-
ing the Erase operation, the only valid read is Toggle Bit or Data# Polling. See Table 4 for the command
sequence, Figure 9 for the timing diagram, and Figure 20 for the flowchart. Any commands issued dur-
ing the Chip-Erase operation are ignored.
Write Operation Status Detection
To optimize the system write cycle time, the SST39WF800B provides two software means to detect the
completion of a Program or Erase write cycle. The software detection includes two status bits—Data#
Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode is enabled after the rising edge
of WE#, which initiates the internal Program or Erase operation.
The completion of the nonvolatile Write is asynchronous with the system; therefore, either a Data#
Polling or Toggle Bit read may occur simultaneously with the completion of the Write cycle. If this
occurs, the system may get an erroneous result, i.e., valid data may appear to conflict with either DQ7
or DQ6. To prevent spurious rejection in the event of an erroneous result, the software routine must
include a loop to read the accessed location an additional two (2) times. If both Reads are valid, then
the device has completed the Write cycle, otherwise the rejection is valid.

Data# Polling (DQ7)
When the SST39WF800B is in the internal Program operation, any attempt to read DQ7will produce
the complement of the true data. Once the Program operation is complete, DQ7will produce true data.
Although DQ7may have valid data immediately following the completion of an internal Write operation,
the remaining data outputs may still be invalid. Valid data on the entire data bus will appear in subse-
quent successive Read cycles after an interval of 1 µs.During an internal Erase operation, any attempt
to read DQ7will produce a ‘0’. Once the internal Erase operation is complete, DQ7will produce a ‘1’.
The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For
Sector-, Block-, or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#)
pulse. See Figure 8 for Data# Polling timing diagram and Figure 18 for a flowchart.
Toggle Bit (DQ6)
During the internal Program or Erase operation, any consecutive attempts to read DQ6will produce
alternating ‘1’s and ‘0’s, i.e., toggling between ‘1’ and ‘0’.
When the Program or Erase operation is complete, the DQ6bit will stop toggling and the device is
ready for the next operation.
The Toggle Bit is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For
Sector-, Block- or Chip-Erase, the Toggle Bit is valid after the rising edge of sixth WE# (or CE#) pulse.
See Figure 0-1 for Toggle Bit timing diagram and Figure 18 for a flowchart.
Data Protection
The SST39WF800B provides both hardware and software features to protect nonvolatile data from
inadvertent writes.
Hardware Data Protection
Noise/Glitch Protection: A WE# or CE# pulse of less than 5 ns will not initiate a write cycle.
VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 1.0V.
Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This pre-
vents inadvertent writes during power-up or power-down.
Software Data Protection (SDP)
The SST39WF800B provides the JEDEC approved Software Data Protection scheme for all data alter-
ation operations, i.e., Program and Erase. Any Program operation requires the inclusion of the three-
byte sequence. The three-byte load sequence is used to initiate the Program operation, providing opti-
mal protection from inadvertent Write operations, e.g., during the system power-up or power-down.
Any Erase operation requires the inclusion of six-byte sequence. This group of devices are shipped
with the Software Data Protection permanently enabled. See Table 4 for the specific software com-
mand codes. During SDP command sequence, invalid commands will abort the device to Read mode
within TRC. The contents of DQ15-DQ8can be VIL or VIH, but no other value, during any SDP command
sequence.

Common Flash Memory Interface (CFI)
The SST39WF800A contains the CFI information that describes the characteristics of the device, and
supports both the original SST CFI Query mode implementation for compatibility with existing SST
devices, as well as the general CFI Query mode.
To enter the SST CFI Query mode, the system must write the three-byte sequence, same as the Prod-
uct ID Entry command, with 98H (CFI Query command) to address 5555H in the last byte sequence.
To enter the general CFI Query mode, the system must write a one-byte sequence using the Entry
command with 98H to address 55H.
Once the device enters the CFI Query mode, the system can read CFI data at the addresses given in
Tables 5 through 7. The system must write the CFI Exit command to return to Read mode from the CFI
Query mode.
Product Identification
The Product Identification mode identifies the device as the SST39WF800B and manufacturer as SST.
This mode is accessed by software operations. Use Software Product Identification operation to iden-
tify the part (i.e., using the device ID) when using multiple manufacturers in the same socket. For
details, see Table 4 for software operation, Figure 12 for the Software ID Entry and Read timing dia-
gram, and Figure 19 for the Software ID Entry command sequence flowchart.
Product Identification Mode Exit/CFI Mode Exit
To return to the standard Read mode, exit the Software Product Identification mode. Issue the Soft-
ware ID Exit command sequence which returns the device to the Read mode.
The Software ID Exit command may also be used to reset the device to the Read mode after any inad-
vertent transient condition that causes the device to behave abnormally, e.g., not read correctly.
The Software ID Exit/CFI Exit command is ignored during an internal Program or Erase operation. See
Table 4 for software command codes, Figure 14 for timing waveform, and Figure 19 for a flowchart.
