General Description
ASI’s AS5SP128K36DQ is a 4.5Mb High Performance Synchronous Pipeline Burst SRAM, available in multiple temperature screening levels, fabricated using High Performance CMOS technology and is organized as a 128K x 36. It integrates address and control registers, a two (2) bit burst address counter supporting four (4) double-word transfers. Writes are internally self-timed and synchronous to the rising edge of clock.
