Functional Description
The CY7C1325H is a 256K × 18 synchronous cache RAM designed to interface with high speed microprocessors with minimum glue logic. Maximum access delay from clock rise is
6.5 ns (133 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...
