MOS INTEGRATED CIRCUIT
μPD70F3735, 70F3736, 70F3737, 70F3738
V850ES/JF3-L, V850ES/JG3-L
32-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The μPD70F3735, 70F3736 (V850ES/JF3-L), and μPD70F3737, 70F3738 (V850ES/JG3-L) are products of the
V850 32-bit single-chip microcontrollers, and include peripheral functions such as ROM/RAM, timer/counters, serial
interfaces, an A/D converter, a D/A converter, and a DMA controller.
In addition to their high real-time responsiveness and one-clock-pitch execution of instructions, the V850ES/JF3-L,
and V850ES/JG3-L include instructions suited to digital servo control applications such as multiplication instructions
executed via a hardware multiplier, saturation instructions, and bit manipulation instructions. As a real-time control
system, this device enables an extremely high cost-performance for applications that require low power consumption,
such as digital camera, electrical power-meter, and mobile phone.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
