The high-speed V852 microcontroller features the high-performance 32-bit RISC engine of NEC’s V850
family and targets low-power designs with large embedded code. The device has nearly three times the
on-chip memory of the V851
(90K versus 32K of ROM and 3K versus 1K of RAM). Many versions of
the V850 core are available as part of NEC’s ASIC library. The architecture of the V852 device is highly
optimized for fast DSP-like operation and very efficient implementation of C programmability.
