Product Summary
The CY7C1338G-133AXI is a 131,072 x 32 synchronous cache RAM designed to interface with high-speed microprocessor with minimum glue logic. Maximum access delay of the CY7C1338G-133AXI 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 by registers controlled by a positive-edge-triggered Clock Input (CLK).
