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
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-pin
PLCC, 32-pin TSOP and 28-pin PDIP packages. The
SST27SF010/020 are offered in 32-pin PDIP 32-pin PLCC
and 32-pin TSOP packages. See Figures 1, 2, and 3 for
pinouts.
Device Operation
The SST27SF256/512/010/020 are a low cost flash solu-
tion 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 stan-
dard EPROM products. In addition to EPROM functionality,
these devices also support electrical 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.
Byte-Program Operation
The SST27SF256/512/010/020 are programmed by using
an external programmer. The programming mode for
SST27SF256/010/020 is activated by asserting 12V (±5%)
