DESCRIPTION
The IDT71V256SA is a 262,144-bit high-speed static RAM
organized as 32K x 8. It is fabricated using IDT鈥檚 high-
performance, high-reliability CMOS technology.
The IDT71V256SA has outstanding low power character-
istics while at the same time maintaining very high perfor-
mance. Address access times of as fast as10 ns are ideal for
3.3V secondary cache in 3.3V desktop designs.
When power management logic puts the IDT71V256SA in
standby mode, its very low power characteristics contribute to
extended battery life. By taking
CS
HIGH, the SRAM will
automatically go to a low power standby mode and will remain
in standby as long as
CS
remains HIGH. Furthermore, under
full standby mode (
CS
at CMOS level, f=0), power consump-
tion is guaranteed to always be less than 6.6mW and typically
will be much smaller.
The IDT71V256SA is packaged in 28-pin 300 mil SOJ, 28-
pin 300 mil plastic DIP, and 28-pin 300 mil TSOP Type I
packaging.
