The CY7C1338G is a 131,072 x 32 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic.
The CY7C1338G is a 4-Mbit (128K x 32) synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic. It provides fast clock-to-output times, ranging from 6.5 ns for the 133-MHz version to 8.0 ns for the 100-MHz version. The device supports user-selectable burst counters for Intel Pentium interleaved or linear burst sequences.

It supports user-selectable burst counters for Intel Pentium interleaved or linear burst sequences.
The burst order is determined by sampling the MODE input; HIGH selects interleaved, and LOW selects linear.
The device is available in 133-MHz, 117-MHz, and 100-MHz versions.
