WCSS0418V1F - 256K x 18 Synchronous 3.3V Cache RAM

General Description

The WCSS0418V1F is a 3.3V, 256K by 18 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic.

Maximum access delay from clock rise is 7.5 ns (117-MHz version).

Key Features

  • Supports 117-MHz microprocessor cache systems with zero wait states.
  • 256K by 18 common I/O.
  • Fast clock-to-output times.
  • 7.5 ns (117-MHz version).
  • Two-bit wrap-around counter supporting either interleaved or linear burst sequence www. DataSheet4U. com.
  • Separate processor and controller address strobes provide direct interface with the processor and external cache controller.
  • Synchronous self-timed write.
  • Asynchronous output en.
