DESCRIPTION

The ICSI IS61SF6432 is a high-speed, low-power synchronous static RAM designed to provide a burstable, high-performance, secondary cache for the Pentium?, 680X0?, and PowerPC? microprocessors. It is organized as 65,536 words by 32 bits, fabricated with ICSIs advanced CMOS technology. The device integrates a 2-bit burst counter, high-speed SRAM core, and high-drive capability outputs into a single monolithic circuit. All synchronous inputs pass through registers controlled by a positive-edge-triggered single clock input.

FEATURES

? Fast access time: 9 ns, 10 ns

? Internal self-timed write cycle

? Individual Byte Write Control and Global Write

? Clock controlled, registered address, data and control

? Pentium? or linear burst sequence control using MODE input

? Three chip enables for simple depth expansion and address pipelining

? Common data inputs and data outputs

? Power-down control by ZZ input

? JEDEC 100-Pin LQFP and PQFP package

? Single +3.3V power supply

? Two Clock enables and one Clock disable to eliminate multiple bank bus contention.

? Control pins mode upon power-up:

– FT in pipeline mode – MODE in interleave burst mode

– ZZ in normal operation mode

These control pins can be connected to GNDQ or VCCQ to alter their power-up state

? Industrial temperature available
