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 characteristics while
at the same time maintaining very high performance. Address access
times of as fast as 10ns 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. Further-
more, 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 a 28-pin 300 mil SOJ and a 28-pin
300 mil TSOP Type I.
