The V850E/MS1 microcontroller offers on-chip external memory support for NEC’s V850 family of
32-bit RISC microcontrollers. With a CPU capable of operating at 52 million instructions per second
(MIPS), this device is targeted for wireless communication and other high-performance, power-sensi-
tive, portable applications. Advanced two-cycle external memory access, DMA controllers,
DRAM/ROM controllers, 128K of on-chip flash memory, and a variety of integrated peripherals make
the V850E/MS1 device highly optimized for efficient implementation of C programmability. The V850E
core is also available as part of NEC’s ASIC library.
