Functional Description[1]

The CY7C1481V25/CY7C1483V25/CY7C1487V25 is a 2.5V, 2M x 36/4M x 18/1M x 72 Synchronous Flow-through SRAM 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.
