32-/16-BIT SINGLE-CHIP MICROCONTROLLERS
TM
The
µ
PD703037A, 703037AY, 70F3037A, and 70F3037AY (V850/SB2) are 32-/16-bit single-chip microcontrollers
of the V850 Family
TM
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
µ
PD70F3037A and 70F3037AY have flash memory in place of the internal mask ROM of the
µ
PD703037A
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
µ
PD703034A, 703034AY, 703035A, 703035AY, 70F3035A, and 70F3035AY with different ROM/RAM
capacity are also available.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
