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 synchronous inputs include all addresses, all data inputs, active LOW chip enable (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).
