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.
