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. FEATURES • • • • • • • • • • • Software compatible with V25 Software compatible 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 : 250 ns/8 MHz (external 16 MHz) : 200 ns/10 MHz (externa [ ... ]
