Functional Description
The CY7C1461AV33/CY7C1463AV33/CY7C1465AV33[1] are 3.3V, 1M x 36/2M x 18/512K x 72 Synchronous Flow-Through Burst SRAMs designed specifically to support unlimited true back-to-back read and write operations without the insertion of wait states. The CY7C1461AV33/CY7C1463AV33/CY7C1465AV33 is equipped with the advanced NoBL logic required to enable consecutive read and write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data through the SRAM, especially in systems that require frequent write-read transitions.
