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 7.5 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.

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
