The NEC V25 (μPD70320) is the microcontroller version of the NEC V20 processor, manufactured by NEC Corporation. Features include:
- NEC V20 core: 8-bit external data path, 20-bit address bus, machine code compatible with the Intel 8088 (the processor used in the original IBM PC)
- On-chip peripheral hardware mapped in memory address space
- Two-channel 16-bit timers
- Internal interrupt controller
- Dual-channel UART and baud rate generator for serial communications[1]
- Eight register banks[2]
- Two-channel DMA controller[3]
It was officially phased out by NEC in early 2003.[4]
