The V831 microcontroller is the second member of NEC’s V830
family of 32-bit RISC micro-
controllers. This high-performance, low-power microcontroller is well suited for embedded, image
processing and networking applications. The V831 device integrates the V830 microprocessor core
with on-chip external memory support and standard peripherals that include a DMA controller,
DRAM/EDO/page-mode ROM controllers, UART, clocked serial interface, and timers. With its
on-board peripherals, the V831 microcontroller provides a cost-effective solution for consumer
electronics applications.
