DESCRIPTION

The M66252P/FP is a high-speed line memory with a FIFO (First In First Out) structure of 1152-word × 8-bit configuration which uses high-performance silicon gate CMOS process technology.

It has separate clock, enable and reset signals for write and read and is most suitable as a buffer memory between devices with different data processing throughput.
