PRODUCT DESCRIPTION

The SST39WF1601/1602 devices are 1M x16 CMOS

Multi-Purpose Flash Plus (MPF+) manufactured with

SST’s proprietary, high-performance CMOS SuperFlash

technology. The split-gate cell design and thick-oxide tun-

neling injector attain better reliability and manufacturability

compared with alternate approaches. The SST39WF1601/

1602 write (Program or Erase) with a 1.65-1.95V power

supply. These devices conform to JEDEC standard pin

assignments for x16 memories.

Featuring high performance Word-Program, the

SST39WF1601/1602 devices provide a typical Word-Pro-

gram time of 28 µsec. These devices use Toggle Bit or

Data# Polling to indicate the completion of Program opera-

tion. To protect against inadvertent write, they have on-chip

hardware and Software Data Protection schemes.

Designed, manufactured, and tested for a wide spectrum of

applications, these devices are offered with a guaranteed

typical endurance of 100,000 cycles. Data retention is rated

at greater than 100 years.

The SST39WF1601/1602 devices are suited for applica-

tions that require convenient and economical updating of

program, configuration, or data memory. For all system

applications, they significantly improve performance and

reliability, while lowering power consumption. They inher-

ently use less energy during Erase and Program than

alternative flash technologies. The total energy consumed

is a function of the applied voltage, current, and time of

application. Since for any given voltage range, the Super-

Flash technology uses less current to program and has a

shorter erase time, the total energy consumed during any

Erase or Program operation is less than alternative flash

technologies. These devices also improve flexibility while

lowering the cost for program, data, and configuration stor-

age applications.

The SuperFlash technology provides fixed Erase and Pro-

gram times, independent of the number of Erase/Program

cycles that have occurred. Therefore 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 high density, surface mount requirements, the

SST39WF1601/1602 are offered in both 48-ball TFBGA

and 48-ball WFBGA packages. See Figures 2 and 3 for

pin assignments.

Device Operation

Commands are used to initiate the memory operation func-

tions of the device. Commands are written to the device

using standard microprocessor write sequences. A com-

mand 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.

The SST39WF1601/1602 also have the Auto Low Power

mode which puts the device in a near standby mode after

data has been accessed with a valid Read operation. This

reduces the IDD active read current from typically 9 mA to

typically 5 µA. The Auto Low Power mode reduces the typi-

cal IDD active read current to the range of 2 mA/MHz of

Read cycle time. The device exits the Auto Low Power

mode with any address transition or control signal transition

used to initiate another Read cycle, with no access time

penalty. Note that the device does not enter Auto-Low

Power mode after power-up with CE# held steadily low,

until the first address transition or CE# is driven high.

Read

The Read operation of the SST39WF1601/1602 is con-

trolled by CE# and OE#, both have to be low for the sys-

tem to obtain data from the outputs. CE# is used for

device selection. When CE# is high, the chip is dese-

lected 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 impedance state when

either CE# or OE# is high. Refer to the Read cycle timing

diagram for further details (Figure 4).

Word-Program Operation

The SST39WF1601/1602 are programmed on a word-by-

word basis. Before programming, the sector where the

word exists must be fully erased. The Program operation is

accomplished in three steps. The first step is the three-byte

load sequence for Software Data Protection. The second

step is to 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. The third step is the internal

Program operation which is initiated after the rising edge of

the fourth WE# or CE#, whichever occurs first. The Pro-

gram operation, once initiated, will be completed within 40

µs. See Figures 5 and 6 for WE# and CE# controlled Pro-

gram operation timing diagrams and Figure 20 for flow-

charts. During the Program operation, the only valid reads

are Data# Polling and Toggle Bit. During the internal Pro-

gram operation, the host is free to perform additional tasks.

Any commands issued during the internal Program opera-

tion are ignored. During the command sequence, WP#

should be statically held high or low.

Sector/Block-Erase Operation

The Sector- (or Block-) Erase operation allows the system

to erase the device on a sector-by-sector (or block-by-

block) basis. The SST39WF1601/1602 offer both Sector-

Erase and Block-Erase modes. The sector architecture is

based on uniform sector size of 2 KWord. The Block-Erase

mode is based on uniform block size of 32 KWord. The

Sector-Erase operation is initiated by executing a six-byte

command sequence with Sector-Erase command (30H)

and sector address (SA) in the last bus cycle. The Block-

Erase operation is initiated by executing a six-byte com-

mand 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 and Figure 24 for the flowchart. Any

commands issued during the Sector- or Block-Erase oper-

ation are ignored. When WP# is low, any attempt to Sector-

(Block-) Erase the protected block will be ignored. During

the command sequence, WP# should be statically held

high or low.

SST39WF1601 / SST39WF1602

Erase-Suspend/Erase-Resume Commands

The Erase-Suspend operation temporarily suspends a

Sector- or Block-Erase operation thus allowing data to be

read from any memory location, or program data into any

sector/block that is not suspended for an Erase operation.

The operation is executed by issuing one byte command

sequence with Erase-Suspend command (B0H). The

device automatically enters read mode typically within 20

µs after the Erase-Suspend command had been issued.

Valid data can be read from any sector or block that is not

suspended from an Erase operation. Reading at address

location within erase-suspended sectors/blocks will output

DQ2 toggling and DQ6 at “1”. While in Erase-Suspend

mode, a Word-Program operation is allowed except for the

sector or block selected for Erase-Suspend.

To resume Sector-Erase or Block-Erase operation which has

been suspended the system must issue Erase Resume

command. The operation is executed by issuing one byte

command sequence with Erase Resume command (30H)

at any address in the last Byte sequence.

Chip-Erase Operation

The SST39WF1601/1602 provide a Chip-Erase operation,

which allows the user to erase the entire memory array to

the “1” state. This is useful when the entire device must be

quickly erased.

The Chip-Erase operation is initiated by executing a six-

byte command sequence with Chip-Erase command

(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. During the Erase

operation, the only valid read is Toggle Bit or Data# Polling.

See Table 6 for the command sequence, Figure 10 for tim-

ing diagram, and Figure 24 for the flowchart. Any com-

mands issued during the Chip-Erase operation are

ignored. When WP# is low, any attempt to Chip-Erase will

be ignored. During the command sequence, WP# should

be statically held high or low.

Write Operation Status Detection

The SST39WF1601/1602 provide two software means to

detect the completion of a Write (Program or Erase) cycle,

in order to optimize the system write cycle time. The soft-

ware 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 ini-

tiates the internal Program or Erase operation.

The actual completion of the nonvolatile write is asyn-

chronous with the system; therefore, either a Data# Poll-

ing or Toggle Bit read may be simultaneous with the

completion of the write cycle. If this occurs, the system

may possibly get an erroneous result, i.e., valid data may

appear to conflict with either DQ7 or DQ6. In order to pre-

vent spurious rejection, if an erroneous result occurs, the

software routine should 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 SST39WF1601/1602 are in the internal Pro-

gram operation, any attempt to read DQ7 will produce the

complement of the true data. Once the Program operation

is completed, DQ7 will produce true data. Note that even

though DQ7 may 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 subsequent successive Read

cycles after an interval of 1 µs. During internal Erase oper-

ation, any attempt to read DQ7 will produce a ‘0’. Once the

internal Erase operation is completed, DQ7 will 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 7 for

Data# Polling timing diagram and Figure 21 for a flowchart.

Data Sheet

16 Mbit Multi-Purpose Flash Plus

SST39WF1601 / SST39WF1602

Toggle Bits (DQ6 and DQ2)

During the internal Program or Erase operation, any con-

secutive attempts to read DQ6 will produce alternating “1”s

and “0”s, i.e., toggling between 1 and 0. When the internal

Program or Erase operation is completed, the DQ6 bit will

stop toggling. The device is then ready for the next opera-

tion. For Sector-, Block-, or Chip-Erase, the toggle bit (DQ6)

is valid after the rising edge of sixth WE# (or CE#) pulse.

DQ6 will be set to “1” if a Read operation is attempted on an

Erase-Suspended Sector/Block. If Program operation is ini-

tiated in a sector/block not selected in Erase-Suspend

mode, DQ6 will toggle.

An additional Toggle Bit is available on DQ2, which can be

used in conjunction with DQ6 to check whether a particular

sector is being actively erased or erase-suspended. Table 1

shows detailed status bits information. The Toggle Bit

(DQ2) is valid after the rising edge of the last WE# (or CE#)

pulse of Write operation. See Figure 8 for Toggle Bit timing

diagram and Figure 21 for a flowchart.

Note: DQ7 and DQ2 require a valid address when reading

status information.

Data Protection

The SST39WF1601/1602 provide both hardware and soft-

ware 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 1.5V.

Write Inhibit Mode: Forcing OE# low, CE# high, or WE#

high will inhibit the Write operation. This prevents inadvert-

ent writes during power-up or power-down.

Hardware Block Protection

The SST39WF1602 support top hardware block protec-

tion, which protects the top 32 KWord block of the device.

The SST39WF1601 support bottom hardware block pro-

tection, which protects the bottom 32 KWord block of the

device. The Boot Block address ranges are described in

Table 2. Program and Erase operations are prevented on

the 32 KWord when WP# is low. If WP# is left floating, it is

internally held high via a pull-up resistor, and the Boot

Block is unprotected, enabling Program and Erase opera-

tions on that block.

Hardware Reset (RST#)

The RST# pin provides a hardware method of resetting the

device to read array data. When the RST# pin is held low

for at least TRP, any in-progress operation will terminate and

return to Read mode. When no internal Program/Erase

operation is in progress, a minimum period of TRHR is

required after RST# is driven high before a valid Read can

take place (see Figure 16).

The Erase or Program operation that has been interrupted

needs to be reinitiated after the device resumes normal

operation mode to ensure data integrity.

Software Data Protection (SDP)

The SST39WF1601/1602 provide the JEDEC approved

Software Data Protection scheme for all data alteration

operations, i.e., Program and Erase. Any Program opera-

tion requires the inclusion of the three-byte sequence. The

three-byte load sequence is used to initiate the Program

operation, providing optimal 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. These devices are shipped with the

Software Data Protection permanently enabled. See Table

6 for the specific software command codes. During SDP

command sequence, invalid commands will abort the

device to read mode within TRC. The contents of DQ15-DQ8

can be VIL or VIH, but no other value, during any SDP com-

mand sequence.

SST39WF1601 / SST39WF1602

Common Flash Memory Interface (CFI)

The SST39WF1601/1602 contain the CFI information to

describe the characteristics of the device. The

SST39WF1601/1602 support the original SST CFI Query

mode implementation for compatibility with existing SST

devices as well as the general CFI Query mode. Both will

be explained in subsequent paragraphs.

In order to enter the SST CFI Query mode, the system

must write the three-byte sequence, same as the product

ID entry command with 98H (CFI Query command) to

address 5555H in the last byte sequence. Once the device

enters CFI Query mode, the system can read CFI data at

the addresses given in Tables 7 through 9. The system

must write the CFI Exit command to return to Read mode

from the CFI Query mode.

In order to enter the general CFI Query mode, the system

must write a one-byte sequence with 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 7 through 9. 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 devices as

the SST39WF1601, SST39WF1602 and manufacturer as

SST. This mode may be accessed software operations.

Users may use the Software Product Identification opera-

tion to identify the part (i.e., using the device ID) when

using multiple manufacturers in the same socket. For

details, see Table 6 for software operation, Figure 12 for

the Software ID Entry and Read timing diagram and Fig-

ure 22 for the Software ID Entry command sequence

flowchart.

Product Identification Mode Exit/

CFI Mode Exit

In order to return to the standard Read mode, the Software

Product Identification mode must be exited. Exit is accom-

plished by issuing the Software ID Exit command

sequence, which returns the device to the Read mode.

This command may also be used to reset the device to the

Read mode after any inadvertent transient condition that

apparently causes the device to behave abnormally, e.g.,

not read correctly. Please note that the Software ID Exit/

CFI Exit command is ignored during an internal Program or

Erase operation. See Table 6 for software command

codes, Figure 14 for timing waveform, and Figures 22 and

23 for flowcharts.

Security ID

The SST39WF1601/1602 devices offer a 256-bit Security

ID space. The Secure ID space is divided into two 128-bit

segments - one factory programmed segment and one

user programmed segment. The first segment is pro-

grammed and locked at SST with a random 128-bit num-

ber. The user segment is left un-programmed for the

customer to program as desired.

To program the user segment of the Security ID, the user

must use the Security ID Word-Program command. To

detect end-of-write for the SEC ID, read the toggle bits. Do

not use Data# Polling. Once this is complete, the Sec ID

should be locked using the User Sec ID Program Lock-Out.

This disables any future corruption of this space. Note that

regardless of whether or not the Sec ID is locked, neither

Sec ID segment can be erased.

The Secure ID space can be queried by executing a three-

byte command sequence with Enter Sec ID command

(88H) at address 5555H in the last byte sequence. To exit

this mode, the Exit Sec ID command should be executed.
