V850E/IG4和V850E/IH4: 32-bit Single-Chip Microcontrollers

The V850E/IG4 and V850E/IH4 are 32-bit single-chip microcontrollers that use the V850E1 CPU core and incorporate ROM/RAM and various peripheral functions such as DMA controller, timer/counter, watchdog timer, serial interfaces, A/D converter, and on-chip debug function.

In addition to high real-time response characteristics and 1-clock-pitch basic instructions, the V850E/IG4 and V850E/IH4 feature instructions such as multiply instructions realized by a hardware multiplier, saturated operation instructions, and bit manipulation instructions, as optimum instructions for digital servo control applications. Moreover,as a real-time control system, the V850E/IG4 and V850E/IH4 enable an extremely high cost-performance for applications such as motor inverter control.

O Operating supply voltage: When any A/D converter from 0 to 2 is operating

VDD0 = VDD1 = VDD2 = VDD3 (V850E/IH4 only) = 1.35 to 1.65 V

FVDD (V850E/IH4 only) = 4.0 to 5.5 V

EVDD0 = EVDD1 = EVDD2 = EVDD3 (V850E/IH4 only) = AVDD0 = AVDD1 = AVDD2 = 4.0 to 5.5 V
