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, TSOP, and PDIP 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.

Data Sheet
Byte-Program Operation
Product Identification Mode
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-bybyte until the entire chip has been programmed. Refer to
Figure 10 for the flowchart and Figure 6 for the timing diagram.
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.
TABLE 1: PRODUCT IDENTIFICATION
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 Chip-Erase
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 FFH. 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.
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.

397 ILL F06.1
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 V) and VOT (0.5 VDD). Input rise and fall times (10% ↔ 90%) are <5 ns.
Note: VIT - VINPUT Test
VOT - VOUTPUT Test
VIHT - VINPUT HIGH Test
VILT - VINPUT LOW Test
