MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66257FP M66257FP 5120 × 8-BIT 2 LINE MEMORY (FIFO) 5120 × 8-BIT × 2×LINE MEMORY (FIFO) DESCRIPTION The M66257FP is a high-speed line memory with a FIFO (First In First Out) structure of 5120-word × 8-bit double configuration which uses high-performance silicon gate CMOS process technology. It allows simultaneous output of 1-line delay data and 2-line delay data, and is most suitable for data correction over multiple lines. 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.
