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 programmer 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 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 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. (c)2001 Silicon Storage Technology, Inc. S71152-02-000 5/01 502 1 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 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 (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 A 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%) The SST logo and SuperFlash are registered trademarks of Silicon Storage Technology, Inc.

The programming mode for SST27SF512 is activated by asserting 12V (5%) on OE#/VPP pin, VDD = 5V (5%), and VIL on CE# pin. These devices are programmed byte-by-byte with the desired data at the desired address using a single pulse (CE# pin low for SST27SF256/512 and PGM# pin low for SST27SF010/ 020) of 20 s. Using the MTP programming algorithm, the Byte-Programming process continues byte-by-byte until the entire chip has been programmed. Product Identification Mode The Product Identification mode identifies the devices as the SST27SF256, SST27SF512, SST27SF010 and SST27SF020 and manufacturer as SST. This mode may be accessed by the hardware method. To activate this mode for SST27SF256/010/020, the programming equipment must force VH (12V5%) on address A9 with VPP pin at VDD (5V10%) or VSS. To activate this mode for SST27SF512, the programming equipment must force VH (12V5%) on address A9 with OE#/VPP pin at VIL. Two identifier bytes may then be sequenced from the device outputs by toggling address line A0. For details, see Tables 3, 4, and 5 for hardware operation. TABLE 1: PRODUCT IDENTIFICATION Address Manufacturer's ID Device ID SST27SF256 SST27SF512 SST27SF010 SST27SF020 0001H 0001H 0001H 0001H A3H A4H A5H A6H T1.1 502 Chip-Erase Operation The only way to change a data from a "0" to "1" is by electrical erase that changes every bit in the device to "1". Unlike traditional EPROMs, which use UV light to do the ChipErase, the SST27SF256/512/010/020 uses an electrical Chip-Erase operation. This saves a significant amount of time (about 30 minutes for each Erase operation). The entire chip can be erased in a single pulse of 100 ms (CE# pin low for SST27SF256/512 and PGM# pin for SST27SF010/020). In order to activate the Erase mode for SST27SF256/010/020, the 12V (5%) is applied to VPP and A9 pins, VDD = 5V (5%), VIL on CE# pin, and VIH on OE# pin. In order to activate Erase mode for SST27SF512, the 12V (5%) is applied to OE#/VPP and A9 pins, VDD = 5V (5%), and VIL on CE# pin. All other address and data pins are "don't care". The falling edge of CE# (PGM# for SST27SF010/020) will start the Chip-Erase operation. Once the chip has been erased, all bytes must be verified for FFH. Refer to Figures 13, 14, and 15 for the flowcharts. Data BFH 0000H (c)2001 Silicon Storage Technology, Inc.
