32-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD703034A, 703034AY, 703035A, 703035AY, 70F3035A, and 70F3035AY (V850/SB2) are 32-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.
The µPD703037A, 703037AY, 70F3037A, 70F3037AY, products with a different ROM/RAM size are also
available.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
