CY7C1338B - 128K x 32 Synchronous-Flow-Through 3.3V Cache RAM

Description

The CY7C1338B is a 3.3V, 128K by 32 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).

Features

  • Supports 117-MHz microprocessor cache systems with zero wait states.
  • 128K by 32 common I/O.
  • Fast clock-to-output times.
  • 7.5 ns (117-MHz version).
  • Two-bit wraparound counter supporting either interleaved or linear burst sequence.
  • Separate processor and controller address strobes provide direct interface with the processor and external www. DataSheet4U. com cache controller.
  • Synchronous self-timed write.
  • Asynchronous output ena.
