M66256中文资料三菱电机数据手册PDF规格书

DESCRIPTION

The M66256FP is a high-speed line memory with a FIFO (First In First Out) structure of 5120-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.
