32-BIT MICROCONTROLLER
The
µ
PD705100 (also called V830) is a microcontroller for incorporation use, which belongs to the V830 family
TM
of the NEC original V800 series
TM
microcontrollers. The V830 can achieve high cost-performance for multimedia
equipment, by integrating quick real-time responses, high-speed arithmetic/logical instructions, and functions suitable
for individual applications.
The following user’s manual describes details of the functions of the V830. Be sure to read it before
designing an application system.
