Description

These are single-chip 16-bit microcomputers designed with high-performance CMOS silicon gate technology, including the internal flash memory and being packaged in 42-pin plastic molded SSOP or shrink plastic molded DIP. These microcomputers 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 7900 Series 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 microcomputers are suitable for office, business, and industrial equipment controller that require high-speed processing of large data. Also, 7900 Series are suitable for motor-control equipment since each of them includes the motor control circuit.

For the internal flash memory, single-power-supply programming and erasure, using a PROM programmer or the control by the central processing unit (CPU), is supported. Also, each of 7900 Series has the memory area dedicated for storing a certain software which controls programming and erasure (reprogramming control software). Therefore, on 7900 Series, the program can easily be changed even after 7900 Series are mounted on the board.
