Functional Description

The CY7C13451G is a 128 K × 36 synchronous cache RAM designed to interface with high speed microprocessors with minimum glue logic. The 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).
