Some parametric limits are subject to change. 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 64-pin plastic molded QFP or shrink plastic molded SDIP. 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.
