Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD70325 V25+TM 16/8-BIT SINGLE-CHIP MICROCONTROLLER The µPD70325 (V25+) is a single-chip microcontroller on which 16-bit CPU, RAM, serial interface, timer, DMA controller, interrupt controller, etc.
are all integrated.
The µPD70325 is software compatible with the 16/8-bit singlechip microcontroller µPD70320 (V25TM).
The V25+ greatly improves the DMA responsivity and transfer rate compared to the V25.
