Functional Description

The CY7C1333 is a 3.3V, 64K by 32 Synchronous Flow-Through Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1333 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 data through the SRAM, especially in systems that require frequent Write-Read transitions. The CY7C1333 is pin/functionally compatible to ZBT SRAM MT55L64L32F.
