PRODUCT DESCRIPTION
The SST39VF320 devices are 2M x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST's proprietary,
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 SST39VF320 write (Program or
Erase) with a 2.7-3.6V power supply.
Featuring high performance Word-Program, the
SST39VF320 devices provide a typical Word-Program
time of 7 µsec. The devices use Toggle Bit or Data# Polling
to indicate the completion of Program operation. To protect
against inadvertent write, these devices have on-chip hardware and software data protection schemes. Designed,
manufactured, and tested for a wide spectrum of applications, the SST39VF320 are offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at
greater than 100 years.
The SST39VF320 devices are suited for applications that
require convenient and economical updating of program,
configuration, or data memory. For all system applications,
the SST39VF320 significantly improve performance and
reliability, while lowering power consumption. The
SST39VF320 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 pro©2003 Silicon Storage Technology, Inc.

gram and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than
alternative flash technologies. The devices also improve
flexibility while lowering the cost for program, data, and configuration storage applications.
The SuperFlash technology provides fixed Erase and Program 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
SST39VF320 is offered in 48-lead TSOP and 48-ball
TFBGA packages. See Figures 1 and 2 for pinouts.
Device Operation
Commands are used to initiate the memory operation functions of the device. Commands 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.

32 Mbit Multi-Purpose Flash
SST39VF320
Preliminary Specifications
is based on uniform block size of 32 KWord. The SectorErase 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 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-ofErase operation can be determined using either Data#
Polling or Toggle Bit methods. See Figures 9 and 10 for timing waveforms. Any commands issued during the Sectoror Block-Erase operation are ignored.
The SST39VF320 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 typical 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 SST39VF320 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
impedance state when either CE# or OE# is high. Refer to
the Read cycle timing diagram for further details (Figure 3).
Chip-Erase Operation
The SST39VF320 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 sixbyte 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
4 for the command sequence, Figure 8 for timing diagram,
and Figure 19 for the flowchart. Any commands issued during the Chip-Erase operation are ignored.
Word-Program Operation
The SST39VF320 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 Program operation, once initiated, will be completed within 10
µs. See Figures 4 and 5 for WE# and CE# controlled Program operation timing diagrams and Figure 16 for flowcharts. During the Program operation, the only valid reads
are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to perform additional tasks.
Any commands issued during the internal Program operation are ignored.
Write Operation Status Detection
The SST39VF320 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.
The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a Data# Polling 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 prevent 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.
Sector/Block-Erase Operation
The Sector- (or Block-) Erase operation allows the system
to erase the device on a sector-by-sector (or block-byblock) basis. The SST39VF320 offer both Sector-Erase
and Block-Erase modes. The sector architecture is based
on uniform sector size of 2 KWord. The Block-Erase mode

Data# Polling (DQ7)
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 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 command sequence.
When the SST39VF320 are in the internal Program 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 operation, 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 6 for Data# Polling
timing diagram and Figure 17 for a flowchart.
Common Flash Memory Interface (CFI)
The SST39VF320 also contain the CFI information to
describe the characteristics of the device. In order to
enter the CFI Query mode, the system must load the
three-byte sequence, similar to the Software ID Entry command. The last byte cycle of this command loads 98H (CFI
Query command) to address 5555H. 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.
Toggle Bit (DQ6)
During the internal Program or Erase operation, any consecutive attempts to read DQ6 will produce alternating 1s
and 0s, i.e., toggling between 1 and 0. When the internal
Program or Erase operation is completed, the DQ6 bit will
stop toggling. 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 7 for
Toggle Bit timing diagram and Figure 17 for a flowchart.
Product Identification
The Product Identification mode identifies the devices as
the SST39VF320 and manufacturer as SST. This mode
may be accessed by 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
4 for software operation, Figure 11 for the Software ID
Entry and Read timing diagram, and Figure 18 for the
Software ID Entry command sequence flowchart.
Data Protection
The SST39VF320 provide both hardware and software features to protect nonvolatile data from inadvertent writes.

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 accomplished 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/
