DESCRIPTION

The µPD703034A, 703034AY, 703035A, 703035AY, 70F3035A, and 70F3035AY (V850/SB2) 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 µPD70F3035A and 70F3035AY have flash memory in place of the internal mask ROM of the µPD703035A and 703035AY. 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.
