PRODUCT DESCRIPTION
The SST37VF010/020/040 devices are 128K x8 / 256K x8
/ 512K x8 CMOS, Many-Time Programmable (MTP), low
cost flash, manufactured with SST’s proprietary, high per-
formance CMOS SuperFlash technology. The split-gate
cell design and thick-oxide tunneling injector attain better
reliability and manufacturability compared with alternate
approaches. The SST37VF010/020/040 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 SST37VF010/020/040 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
SST37VF010/020/040 provide a typical Byte-Program time
of 15 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 SST37VF010/020/040 are suited for applications that
require infrequent writes and low power nonvolatile stor-
age. 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 SST37VF010/020/040 are offered in 32-
lead PLCC, 32-lead TSOP, and 32-pin PDIP packages.
See Figures 2, 3, and 4 for pin assignments.
Device Operation
The SST37VF010/020/040 devices are nonvolatile mem-
ory 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 stan-
dard flash products.The device supports electrical Erase
operation via an external programmer.
Read
The Read operation of the SST37VF010/020/040 is con-
trolled 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 out-
put 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 2
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 5 for the timing diagram.

Byte-Program Operation
The SST37VF010/020/040 are programmed by using an
external programmer. The programming mode is activated
by asserting 11.4-12V on OE# pin and VIL on CE# pin.
The device is programmed using a single pulse (WE# pin
low) of 15 µs per byte. Using the MTP programming algo-
rithm, the Byte-Program process continues byte-by-byte
until the entire chip has been programmed. Refer to Figure
11 for the flowchart and Figure 7 for the timing diagram.
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 SST37VF010/020/040 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
11.4-12V 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 oper-
ation. Once the chip has been erased, all bytes must
be verified for FFH. Refer to Figure 10 for the flowchart
and Figure 6 for the timing diagram.
Product Identification Mode
The Product Identification mode identifies the devices as
SST37VF010, SST37VF020, and SST37VF040 and man-
ufacturer as SST. This mode may be accessed by the hard-
ware method. To activate this mode, the programming
equipment must force VH (11.4-12V) 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.
Design Considerations
The SST37VF010/020/040 should have a 0.1 µF 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 dura-
tion of an Erase operation. OE# must remain stable at VH
for the entire duration of the Program operation.
