Functional Description[1]

The CY7C1361C/CY7C1363C is a 3.3V, 256K x 36 and 512K x 18 Synchronous Flowthrough SRAMs, respectively 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.
