Functional Description

The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are 3.3V, 1M x 36/2M x 18/512K x72 Synchronous pipelined burst SRAMs with No Bus Latency™ (NoBL™) logic, respectively. They are designed to support unlimited true back-to-back Read/Write operations with no wait states. The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are equipped with the advanced (NoBL) logic required to enable consecutive Read/Write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data in systems that require frequent Write/Read transitions. The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are pin compatible and functionally equivalent to ZBT devices.
