PRODUCT DESCRIPTION
The SST27SF256/512/010/020 are a 32K x8 / 64K x8 /
128K x8 / 256K x8 CMOS, Many-Time Programmable
(MTP) low cost flash, manufactured with SST’s proprietary,
high performance SuperFlash technology. The split-gate
cell design and thick oxide tunneling injector attain better
reliability and manufacturability compared with alternate
approaches. These MTP devices can be electrically erased
and programmed at least 1000 times using an external pro-
grammer with a 12 volt power supply. They have to be
erased prior to programming. These devices conform to
JEDEC standard pinouts for byte-wide memories.
Featuring high performance Byte-Program, the
SST27SF256/512/010/020 provide a Byte-Program time of
20 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 SST27SF256/512/010/020 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 SST27SF256/512 are offered in 32-lead
PLCC, 32-lead TSOP and 28-pin PDIP packages. The
,
SST27SF010/020 are offered in 32-pin PDIP 32-lead
,
PLCC, and 32-lead TSOP packages. See Figures 1, 2, and
3 for pin assignments.

Device Operation
The SST27SF256/512/010/020 are a low cost flash
solution that can be used to replace existing UV-
EPROM, OTP, and mask ROM sockets. These devices
are functionally (read and program) and pin compatible
with industry standard EPROM products. In addition to
EPROM functionality, these devices also support elec-
trical Erase operation via an external programmer. They
do not require a UV source to erase, and therefore the
packages do not have a window.
Read
The Read operation of the SST27SF256/512/010/020 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 (T
CE
). Data is available at the
output after a delay of T
OE
from the falling edge of OE#,
assuming that CE# pin has been low and the addresses
have been stable for at least T
CE
-T
OE.
When the CE# pin is
high, the chip is deselected and a typical standby current of
10 µA 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.
