The V832 microcontroller is the third member of NEC’s V830
family of 32-bit RISC microcontrollers.
Designed for very low cost and high performance, the 170-MIPS V832 integrates the V830 micro-
processor core with built-in standard peripherals. For supporting fast external memory, it features an
on-chip SDRAM/SRAM controller and supports up to 200 MB/s external bus bandwidth. Other
peripherals include a DMA controller, UART, clocked serial interface, timers, I/O ports, and a page-
mode ROM controller. Target applications for the V832 microcontroller include image processing,
speech processing, soft modem, networking and Internet-based information appliances.
