µPD705100
V830TM
32-BIT MICROCONTROLLER
The µPD705100 (also called V830) is a microcontroller for incorporation use, which belongs to the V830 familyTM
of the NEC original V800 seriesTM 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.
