DESCRIPTION
The M66222 is a mail box that incorporates two complete CMOS
shared memory cells of 128
×
8-bit configuration using high-
performance silicon gate CMOS process technology, and are
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 individually. This product
exclusively performs a write operation from A port and a read operation
from B port for one memory, and a read operation from A port and a
write operation from B port for the other memory.
FEATURES
Memory configuration of 128
×
8 bits
×
2 memory areas
High-speed access, address access time 40ns (typ.)
Complete asynchronous accessibility from ports A and B
Fixed read/write access ports for memory
Completely static operation
Low power dissipation CMOS design
5V single power supply
TTL direct-coupled I/O
3-state output for I/O pins
APPLICATION
Inter-MCU data transfer memory, communication buffer memory
