Functional Description[1]

The CY7C1352G is a 3.3V, 256K x 18 synchronous-pipelined Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1352G 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 the SRAM, especially in systems that require frequent Write/Read transitions.

All synchronous inputs pass through input registers controlled by the rising edge of the clock. All data outputs pass through output 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 ns 250-MHz device .

Write operations are controlled by the two Byte Write Select BW[A:B] 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 provide for easy bank selection and output tri-state control. In order to avoid bus contention, the output drivers are synchronously tri-stated during the data portion of a write sequence.
