Functional Description[1]
The CY7C1338F is a 131,072 x 32 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 6.5 ns (133-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
• 128K X 32 common I/O
• 3.3V –5% and +10% core power supply (VDD)
• 2.5V or 3.3V I/O supply (VDDQ)
• Fast clock-to-output times
    — 6.5 ns (133-MHz version)
    — 7.5 ns (117-MHz version)
    — 8.0 ns (100-MHz version)
    — 11.0 ns (66-MHz version)
