16-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
DESCRIPTION
These are single-chip 16-bit microcomputers designed with high-per-
formance CMOS silicon gate technology, being packaged in 42-pin
plastic molded SSOP or shrink plastic molded DIP. These microcom-
puters support the 7900 Series instruction set, which are enhanced
and expanded instruction set and are upper-compatible with the
7700/7751 Series instruction set.
The CPU of these microcomputers is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. Also, the
bus interface unit of these microcomputers enhances the memory
access efficiency to execute instructions fast. Therefore, these mi-
crocomputers are suitable for office, business, and industrial equip-
ment controller that require high-speed processing of large data.
Also, they are suitable for motor-control equipment since each of
them includes the motor control circuit.
