Cypress Semiconductor, CY7C1372KV33-167A

The Cypress Semiconductor CY7C1372KV33 series are 3.3V, 1M ´ 18 synchronous pipelined burst SRAMs with no bus latency logic, respectively. 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 ZBT
Supports 250 MHz bus operations with zero wait states
Available speed grades are 250, 200, and 166 MHz
Internally self-timed output buffer control to eliminate the need to use asynchronous OE
Fully registered for pipelined operation
Byte write capability
