WCSS0418V1F Datasheet 256K x 18 Synchronous 3.3V Cache RAM

Manufacturer: Weida Semiconductor

Datasheet Details

The WCSS0418V1F is a 3.3V, 256K by 18 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic.

Maximum access delay from clock rise is 7.5 ns (117-MHz version).

A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access.
