Cypress CY7C1345B-117AC

128K x 367.5 ns0°C ~ 70°C（TA）

Overview

Functional DescriptionThe CY7C1345B is a 3.3V, 128K by 36 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). A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access.   • Supports 117-MHz microprocessor cache systems with    zero wait states• 128K by 36 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• Separate processor and controller address strobes    provide direct interface with the processor and external    cache controller• Synchronous self-timed write• Asynchronous output enable• Supports 3.3V & 2.5V I/O levels• ZZ “sleep” mode
