Functional Description[1]

The CY7C1352F is a 3.3V, 256K x 18 synchronous-pipelined Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1352F is equipped with the advanced No Bus Latency? (NoBL?) logic required to enable consecutive Read/Write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of the SRAM, especially in systems that require frequent Write/Read transitions.
