CY7C1338F-133BGC中文资料赛普拉斯数据手册PDF规格书

Functional Description[1]

The CY7C1338F is a 131,072 x 32 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.
