Infineon/CYPRESS CY7C1470BV33-167AXI

The CY7C1470BV33, CY7C1472BV33, and CY7C1474BV33 are 3.3 V, 2Mx36/4Mx18/1Mx72 Synchronous pipelined burst SRAMs with No Bus Latency™ (NoBL™) logic, respectively. They are designed to support unlimited true back-to-back read or write operations with no wait states. The CY7C1470BV33, CY7C1472BV33, and CY7C1474BV33 are equipped with the advanced (NoBL) logic required to enable consecutive read or write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data in systems that require frequent read or write transitions. The CY7C1470BV33, CY7C1472BV33, and CY7C1474BV33 are pin compatible and functionally equivalent to ZBT devices.
