Functional Description [1]
The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F is a 3.3V, 512K x 36 and 1M x 18 synchronous flow through SRAMs, 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.
