Cypress Semiconductor, CY7C1470BV33-167A

The Cypress Semiconductor CY7C1470BV33 are 3.3 V, 2M ´ 36 synchronous pipelined burst SRAMs with no bus latency logic. They are designed to support unlimited true back-to-back read/write operations with no wait states. It is equipped with the advanced logic required to enable consecutive read/write operations with data being transferred on every clock cycle.

Pin-compatible and functionally equivalent to zero bus turnaround
Supports 250-MHz bus operations with zero wait states
Available speed grades are 250, 200, and 167 MHz
Internally self-timed output buffer control to eliminate the need to use asynchronous OE
Fully-registered for pipelined operation
Byte write capability
