The CY7C1351F is a 3.3V, 128K x 36 Synchronous Flow-through Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1351F 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.
All synchronous inputs of CY7C1351F pass through input registers controlled by the rising edge of the clock. The clock input is qualified by the Clock Enable (CEN ) signal, which when deasserted suspends operation and extends the previous clock cycle. Maximum access delay from the clock rise is 6.5 ns (133-MHz device).
Write operations of CY7C1351F are controlled by the four Byte Write Select (BW[A:D]) and a Write Enable (WE) input. All writes are conducted with on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE1, CE2, CE3) and an asynchronous Output Enable (OE )of CY7C1351F provide for easy bank selection and output three-state control. In order to avoid bus contention, the output drivers CY7C1351F are synchronously three-stated during the data portion of a write sequence.
