The μPD703037A, 703037AY, 70F3037A, and 70F3037AY (V850/SB2) are 32-/16-bit single-chip microcontrollers of the V850 Family? 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 μPD70F3037A and 70F3037AY have flash memory in place of the internal mask ROM of the μPD703037A and 703037AY. 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.

The μPD703034A, 703034AY, 703035A, 703035AY, 70F3035A, and 70F3035AY with different ROM/RAM capacity are also available.
