16-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
DESCRIPTION
These are microcomputers designed with high-performance CMOS
silicon gate technology. These microcomputers support the 7900
Series instruction set, which is enhanced and expanded instruction
set and is 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.
