DESCRIPTION

The

µPD703031A, 703031AY, 703033A, 703033AY, 70F3033A, and 70F3033AY (V850/SB1) are 32-/16-bit

single-chip microcontrollers of the V850 Family

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.
