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.  
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.  
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.  
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 (TCE). Data is available at the  
output after a delay of TOE from the falling edge of OE#,  
assuming that 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 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.  
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.
