IDT71V256SA  
LOW POWER  
3.3V CMOS FAST SRAM  
256K (32K x 8-BIT)  
Integrated Device Technology, Inc.  
FEATURES  
• Ideal for high-performance processor secondary cache  
DESCRIPTION  
TheIDT71V256SAisa 262,144-bithigh-speedstaticRAM  
• Commercial (0° to 70°C) and Industrial (-40° to 85°C) organized as 32K x 8. It is fabricated using IDT’s high-  
temperature options  
performance, high-reliability CMOS technology.  
• Fast access times:  
— Commercial: 10/12/15/20ns  
— Industrial: 15ns  
• Low standby current (maximum):  
— 2mA full standby  
• Small packages for space-efficient layouts:  
— 28-pin 300 mil SOJ  
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  
— 28-pin 300 mil plastic DIP (Commercial only)  
— 28-pin TSOP Type I  
• Produced with advanced high-performance CMOS full standby mode (CS at CMOS level, f=0), power consump-  
technology  
• Inputs and outputs are LVTTL-compatible  
• Single 3.3V(±0.3V) power supply  
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.
