Functional Description

[1]

The CY7C1371CV25 is a 2.5V, 512K x 36/ 1M x 18

Synchronous Flow-through Burst SRAM designed specifically

to support unlimited true back-to-back Read/Write operations

without the insertion of wait states. The CY7C1371CV25 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 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 are controlled by the two or four Byte Write

Select (BW

) and a Write Enable (WE) input. All writes are

conducted with on-chip synchronous self-timed write circuitry.

Three synchronous Chip Enables (CE

, CE

) and an

asynchronous Output Enable (OE) provide for easy bank

selection and output three-state control. In order to avoid bus

contention, the output drivers are synchronously three-stated

during the data portion of a write sequence.
