CY7C1471V25 - (CY7C147xV25) 72-Mbit (2M x 36/4M x 18/1M x 72) Flow-Through SRAM

Description

The CY7C1471V25, CY7C1473V25 and CY7C1475V25 are 2.5V, 2M x 36/4M x 18/1M x 72 Synchronous Flow-through Burst SRAMs designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states.

Features

  • No Bus Latency™ (NoBL™) architecture eliminates dead cycles between write and read cycles.
  • Can support up to 133-MHz bus operations with zero wait states.
  • Data is transferred on every clock.
  • Pin compatible and functionally equivalent to ZBT™ devices.
  • Internally self-timed output buffer control to eliminate the need to use OE.
  • Registered inputs for flow-through operation.
  • Byte Write capability.
  • 2.5V/1.8V I/O power supply.
