µPD75112(A), 75116(A) 4-Bit Single Chip-Microcomputer Data Sheet Description The µPD75116(A) is one of the 4-bit single-chip microcomputer 75X series. The µPD75116(A) is a product with the extended ROM capacity of the µPD75108(A). In addition of high-speed operations, it can manipulate data in units of 1, 4 and 8 bits. In particular, the I/O operation of the µPD75116 have been improved by a wide variety of bit control instructions. The µPD75116 is provided with interface inputs/outputs with peripheral circuits having different power voltages, and analog inputs and suitable for controlling automobile electrical equipment, etc. For the µPD75116(A), an on-chip pin-compatible one-time PROM product (µPD75P116) is separately available for system development evaluation. Functions are described in detail in the following User’s Manual, which should be read when carrying out design work. µPD751×× Series User’s Manual: IEM-992 Ordering Code Package Qualty Grade Special Special Special Special µPD75112CW(A)-××× 64-pin plastic shrink DIP (750 mil) µPD75112GF(A)-×××-3BE 64-pin plastic QFP (14 × 20 mm) 64-pin plastic shrink DIP µPD75116CW(A)-××× (750 mil) µPD75116GF(A)-×××-3BE 64-pin plastic QFP (14 × 20 mm) Remarks: ××× is a ROM code number. Please refer to "Quality Grade on NEC Semiconductor Devices" (Document number IEI-1209) published by NEC Corporation to know the specification of quality grade on the devices and its recommended applications. Unless there are any particular functional differences, the µPD75116(A) is described in this document as a representative product.
