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-Pro-
gram 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.
Refer to Figure 4 for the timing diagram.
