UPD70325 Datasheet | NEC

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 patible with the 16/8-bit singlechip microcontroller µPD70320 (V25TM). The V25+ greatly improves the DMA responsivity and transfer rate pared to the V25. Features - - - - - - - - - - - Software patible with V25 Software patible with µPD70108/70116 (in native mode) (some instructions added) Internal 16-bit architecture and external 8-bit data bus 3-stage pipeline method Minimum instruction cycle :...
