Functional Description
The CY7C1441AV33/CY7C1443AV33/CY7C1447AV33[1] are 3.3 V, 1 M × 36/2 M × 18/512 K × 72 Synchronous Flow-through 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.
