Functional Description

The CY7C1338G is a 128 K × 32 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 8.0 ns (100-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. All synchronous inputs are gated by registers controlled by a positive-edge-triggered clock input (CLK).
