M66223FP
MITSUBISHI UNDER DEVELOPMENT M66223FP 4096 x 16-BIT MAIL BOX FEATURES DESCRIPTION The M66223 is a mail box that incorporates a complete CMOS shared memory cell of 4096 x 16-bit configuration using high-performance silicon gate CMOS process technology, and is equipped with two access ports of A and B. Access ports A and B are equipped with independent addresses CS, WE and OE control pins and I/O pins to allow independent and asynchronous read/write operations from/to shared memory individually. This product also incorporates a port adjustment arbitration function in address contention from both ports. Memory configuration of 4096 words x 16 bits Complete asynchronous accessibility from A and B Built-in port arbitration function 5V single power supply Not Ready output pin is provided (open drain output) TTL direct-coupled I/O 3-state output for I/O pins Built-in 2-input NAND gate for public use APPLICATION Inter-MPU data transfer memory, buffer memory for image processing system.
