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.
