GENERAL DESCRIPTION

The AS5SS256K36 employs high-speed, low-power CMOS

designs that are fabricated using an advanced CMOS process.

This 8Mb Synchronous Burst SRAM integrates a 256K x 36

SRAM core with advanced synchronous peripheral circuitry and a 2-bit

burst counter. All synchronous inputs pass through registers controlled

by a positive-edge-triggered single-clock input (CLK). The synchro-

nous inputs include all addresses, all data inputs, active LOW chip en-

able (CE\), two additional chip enables for easy depth expansion (CE2\,

CE2), burst control inputs (ADSC\, ADSP\, ADV\), byte write enables

(BWx\) and global write (GW\). Note that CE2\ is not available on the

A version.
