The high-performance, low-power V853 microcontroller features the advanced 32-bit RISC engine of
NEC’s V850
family. With 128K of on-chip, single-cycle flash memory, designers have the flexibility to
perform in-system programming of devices, decreasing product development upgrade cycles. The
V853 microcontroller provides a wide array of on-chip peripherals for embedded applications, including
two UARTs, four clocked serial interfaces, three baud rate generators, one 12-bit pulse-width
modulator, one 10-bit A/D converter, and one 8-bit D/A converter. Many versions of the V850 core
are available as part of NEC’s ASIC library. The architecture of the V853 device is highly optimized for
fast DSP-like operation and very efficient implementation of C programmability.
