DATA SHEET MOS INTEGRATED CIRCUIT µPD70433 V55PITM 16-BIT MICROPROCESSOR DESCRIPTION The µPD70433 (V55PI) is a microprocessor in which a 16-bit CPU, RAM, serial interface, parallel interface, A/D converter, timers, DMA controller, interrupt controller, etc., are integrated in a single chip. The V55PI is software-compatible with the µPD70320 and 70330 (V25TM and V35TM) single-chip microcontrollers. The V55PI provides a migration path from the V25. It offers higher-level functions and higher performance, and is particularly suitable for control of data processing systems associated with mechanical control, including printer and facsimile. Detailed functions are described in the following user’s manuals, which should be read when carrying out design work.
