CY7C1338
128K x 32 Synchronous-Flow-Through 3.3V Cache RAM
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 cache controller • Synchronous self-timed write • Asynchronous output enable • 3.3V I/Os • JEDEC-standard pinout • 100-pin TQFP packaging • ZZ “sleep” mode
Functional Description
The CY7C1338 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.
