IS61S6432-5PQI中文资料ICSI数据手册PDF规格书

DESCRIPTION

The ICSI IS61S6432 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

• 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:

– 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
