32-/16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD703031A, 703031AY, 703033A, 703033AY, 70F3033A, and 70F3033AY (V850/SB1) are 32-/16-bit
single-chip microcontrollers of the V850 FamilyTM for AV equipment. 32-bit CPU, ROM, RAM, timer/counters, serial
interfaces, A/D converter, DMA controller, and so on are integrated on a single chip.
The µPD70F3033A and 70F3033AY have flash memory in place of the internal mask ROM of the µPD703033A
and 703033AY. Because flash memory allows the program to be written and erased electrically with the device
mounted on the board, these products are ideal for the evaluation stages of system development, small-scale
production, and rapid development of new products.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
