PRODUCT DESCRIPTION
The SST27VF010/020 are 128K x8 / 256K x8 CMOS,
Many-Time Programmable (MTP) low cost flash, manufac-
tured with SST鈥檚 proprietary, high-performance SuperFlash
technology. The split-gate cell design and thick-oxide tun-
neling 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 programmer with a 12V power sup-
ply. 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
SST27VF010/020 provide a Byte-Program time of 15 碌s.
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 SST27VF010/020 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 SST27VF010/020 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 SST27VF010/020 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 func-
tionality, these devices also support electrical Erase
operation via an external programmer. They do not
require a UV source to erase, and therefore the pack-
ages do not have a window.
Read
The Read operation of the SST27VF010/020 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 out-
put 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
2 碌A(chǔ) 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.
