All non-Pb (lead-free) devices are RoHS compliant
configuration, or data memory. For all system applications,
they significantly improve performance and reliability, while
lowering power consumption. They inherently 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 SuperFlash 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 storage applications.
PRODUCT DESCRIPTION
The SST39VF640xB devices are 4M x16 CMOS Multi-
Purpose Flash Plus (MPF+) manufactured with SST’s pro-
prietary, high-performance CMOS SuperFlash technology.
The split-gate cell design and thick-oxide tunneling injector
attain better reliability and manufacturability compared with
alternate approaches. The SST39VF640xB write (Pro-
gram or Erase) with a 2.7-3.6V power supply. These
devices conform to JEDEC standard pin assignments for
x16 memories.
Featuring high performance Word-Program, the
SST39VF640xB devices provide a typical Word-Program
time of 7 µsec. These devices use Toggle Bit or Data# Poll-
ing to indicate the completion of Program operation. To pro-
tect against inadvertent write, they have on-chip hardware
and Software Data Protection schemes. Designed, manu-
factured, and tested for a wide spectrum of applications,
these devices are offered with a guaranteed typical endur-
ance of 100,000 cycles. Data retention is rated at greater
than 100 years.
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/Pro-
gram cycles.
To meet high-density, surface mount requirements, the
SST39VF640xB devices are offered in 48-lead TSOP and
48-ball TFBGA packages. See Figures 1 and 2 for pin
assignments.
The SST39VF640xB devices are suited for applications that
require convenient and economical updating of program,

Data Sheet
Any commands issued during the internal Program opera-
tion are ignored. During the command sequence, WP#
should be statically held high or low.
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.
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 SST39VF640xB offer both Sector-Erase
and Block-Erase mode. 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 com-
mand sequence with Sector-Erase command (50H) and
sector address (SA) in the last bus cycle. The Block-Erase
operation is initiated by executing a six-byte command
sequence with Block-Erase command (30H) 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 (50H or 30H) 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 9 and 10 for tim-
ing waveforms and Figure 23 for the flowchart. Any com-
mands issued during the Sector- or Block-Erase operation
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.
The SST39VF640xB 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 3 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 SST39VF640xB 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 con-
trol 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 3).
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.
Word-Program Operation
The SST39VF640xB 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 10
µs. See Figures 4 and 5 for WE# and CE# controlled Pro-
gram operation timing diagrams and Figure 19 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.
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.

‘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 6 for
Data# Polling timing diagram and Figure 20 for a flowchart.
Chip-Erase Operation
The SST39VF640xB 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 555H 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 9 for tim-
ing diagram, and Figure 23 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.
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 7 for Toggle Bit timing
diagram and Figure 20 for a flowchart.
Write Operation Status Detection
The SST39VF640xB 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 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.
TABLE 1: WRITE OPERATION STATUS
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.

Note: DQ7 and DQ2 require a valid address when reading

status information.
When the SST39VF640xB are in the internal Program
operation, any attempt to read DQ7 will produce the com-
plement 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

Data Protection
Hardware Reset (RST#)
The SST39VF640xB provide both hardware and software
features to protect nonvolatile data from inadvertent writes.
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 15).
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.
The Erase or Program operation that has been interrupted
needs to be reinitiated after the device resumes normal
operation mode to ensure data integrity.
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.
Software Data Protection (SDP)
The SST39VF640xB provide the JEDEC approved Soft-
ware Data Protection scheme for all data alteration opera-
tions, 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 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.
Hardware Block Protection
The SST39VF6402B support top hardware block protec-
tion, which protects the top 32 KWord block of the device.
The SST39VF6401B 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.

Common Flash Memory Interface (CFI)
The SST39VF640xB also contain the CFI information to
describe the characteristics of the device. In order to enter
the CFI Query mode, the system must write three-byte
sequence, same as product ID entry command with 98H
(CFI Query command) to address 555H in the last byte
sequence. 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
Security ID
The Product Identification mode identifies the devices as
the SST39VF6401B and SST39VF6402B, and the manu-
facturer as SST. This mode may be accessed through
software operations. Users may use the Software Product
Identification operation 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 11 for the Software ID Entry and Read timing dia-
gram and Figure 21 for the Software ID Entry command
sequence flowchart.
The SST39VF640xB devices offer a 256-bit Security ID
space. The Secure ID space is divided into two 128-bit seg-
ments - one factory programmed segment and one user
programmed segment. The first segment is programmed
and locked at SST with a random 128-bit number. The user
segment is left un-programmed for the customer to pro-
gram 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-

(88H) at address 555H in the last byte sequence. To exit
this mode, the Exit Sec ID command should be executed.

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 13 for timing waveform, and Figures 21 and
22 for flowcharts.
