PRODUCT DESCRIPTION
The SST37VF512/010/020/040 devices are 64K x8 /
128K x8 / 256K x8 / 512K x8 CMOS, Many-Time Programmable (MTP), low cost flash, 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 SST37VF512/010/020/040 can be electrically erased
and programmed at least 1000 times using an external
programmer, e.g., to change the contents of devices in
inventory. The SST37VF512/010/020/040 have to be
erased prior to programming. These devices conform to
JEDEC standard pinouts for byte-wide flash memories.
Featuring high performance Byte-Program, the
SST37VF512/010/020/040 provide a typical Byte-Program time of 10 µs. Designed, manufactured, and tested
for a wide spectrum of applications, these devices are
offered with an endurance of at least 1000 cycles. Data
retention is rated at greater than 100 years.
The SST37VF512/010/020/040 are suited for
applications that require infrequent writes and low
power nonvolatile storage. These devices will
improve flexibility, efficiency, and performance while
matching the low cost in nonvolatile applications that
currently use UV-EPROMs, OTPs, and mask ROMs.
To meet surface mount and conventional through hole
requirements, the SST37VF512/010/020/040 are offered in 32-pin PLCC, PDIP and TSOP packages. See
Figures 1, 2 and 3 for pinouts.
Device Operation
The SST37VF512/010/020/040 devices are nonvolatile
memory solutions that can be used instead of standard
flash devices if in-system programmability is not required. It is functionally (Read) and pin compatible with
industry standard flash products.The device supports
electrical Erase operation via an external programmer.
Read
The Read operation of the SST37VF512/010/020/040 is
controlled by CE# and OE#. Both CE# and OE# have to be
low for the system to obtain data from the outputs. Once the
address is stable, the address access time is equal to the
delay from CE# to output (TCE). Data is available at the
output after a delay of TOE from the falling edge of OE#,
assuming the CE# pin has been low and the addresses
have been stable for at least TCE - TOE. When the CE# pin
is high, the chip is deselected and a standby current of only
10 µA (typical) 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 VIH.
Refer to Figure 4 for the timing diagram.
Byte-Program Operation
The SST37VF512/010/020/040 are programmed by using an external programmer. The programming mode is
activated by asserting 12V (±5%) on OE# pin and VIL on
CE# pin. The device is programmed using a single pulse
(WE# pin low) of 10 µs per byte. Using the MTP programming algorithm, the Byte-Program process continues
byte-by-byte until the entire chip has been programmed.
Refer to Figure 10 for the flowchart and Figure 6 for the
timing diagram.

Data Sheet
Chip-Erase Operation
The only way to change a data from a “0” to “1” is by
electrical erase that changes every bit in the device to “1”.
The SST37VF512/010/020/040 use an electrical ChipErase operation. The entire chip can be erased in 100 ms
(WE# pin low). In order to activate erase mode, the 12V
(±5%) is applied to OE# and A9 pins while CE# is low. All
other address and data pins are “don’t care”. The falling
edge of WE# will start the Chip-Erase operation. Once
the chip has been erased, all bytes must be verified for
FF. Refer to Figure 9 for the flowchart and Figure 5 for
the timing diagram.

Design Considerations
The SST37VF512/010/020/040 should have a 0.1µF
ceramic high frequency, low inductance capacitor connected between VDD and GND. This capacitor should be
placed as close to the package terminals as possible.
Product Identification Mode
The Product Identification mode identifies the devices as
SST37VF512, SST37VF010, SST37VF020, and
SST37VF040 and manufacturer as SST. This mode may
be accessed by the hardware method. To activate this
mode, the programming equipment must force VH
(12V±5%) on address A9. Two identifier bytes may then
be sequenced from the device outputs by toggling address line A0. For details, see Table 3 for hardware
operation.
OE# and A9 must remain stable at VH for the entire
duration of an Erase operation. OE# must remain stable
at VH for the entire duration of the Program operation.

AC test inputs are driven at VIHT (0.9 VDD) for a logic “1” and VILT (0.1 VDD) for a logic “0”. Measurement reference points
for inputs and outputs are VIT (0.5 VDD) and VOT (0.5 VDD). Inputs rise and fall times (10%
90%) are <5 ns.
Note: VIT–VINPUT Test
VOT–VOUTPUT Test
VIHT–VINPUT HIGH Test
VILT–VINPUT LOW Test
