IS61SF6432

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(TM) 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

Description

The ICSI IS61SF6432 is a high-speed, low-power synchro- nous static RAM designed to provide a burstable, high-perfor- mance, secondary cache for the Pentium(TM), 680X0(TM), and PowerPC(TM) microprocessors.  IS61SF6432 is organized as 65,536 words by 32 bits, fabricated with ICSI's advanced CMOS technology.
The IS61SF6432 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.

Write cycles are internally self-timed and are initiated by the rising edge of the clock input. Write cycles can be from one to four bytes wide as controlled by the write control inputs.
