IDT71V256SB

3.3V CMOS FAST SRAM

WITH 2.5V COMPATIBLE INPUTS

256K (32K x 8-BIT)

Integrated Device Technology, Inc.

FEATURES

• Ideal for high-performance processor secondary cache

• Fast access times:

— 12/15/20ns

• Inputs are 2.5V and LVTTL compatible: VIH = 1.8V

• Outputs are LVTTL compatible

• Low standby current (maximum):

— 2mA full standby

• Small packages for space-efficient layouts:

— 28-pin 300 mil SOJ

DESCRIPTION

TheIDT71V256SBisa 262,144-bithigh-speedstaticRAM

organized as 32K x 8. The improved VIH (1.8V) makes the

inputs compatible with 2.5V logic levels. The IDT71V256SB

is otherwise identical to the IDT71V256SA.

The IDT71V256SB has outstanding low power character-

istics while at the same time maintaining very high perfor-

mance. Address access times of as fast as12 ns are ideal for

tag SRAM in secondary cache designs.

When power management logic puts the IDT71V256SB in

standby mode, its very low power characteristics contribute to

— 28-pin TSOP Type I

• Produced with advanced high-performance CMOS extended battery life. By taking CS HIGH, the SRAM will

technology

• Single 3.3V(±0.3V) power supply

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 IDT71V256SB is packaged in 28-pin 300 mil SOJ and

28-pin300 mil TSOP Type I packaging.
