The RH850/C1M-A2 microcontroller is equipped with an RH850 Family G3MH dual CPU core, which operates at 320MHz, providing high processing power. Along with the ROM, RAM and DMA, it includes various timers such as a motor control timer, various serial interfaces including CAN (CAN FD compatible), a 12-bit A/D converter (ADC), an R/D converter (RDC3A) that converts the resolver output signal to digital angle data, and a CPU and parallel motor control unit (EMU3), etc., providing peripheral functions that are ideal for motor control in HEVs/EVs. In addition, this product can simultaneously control two motors.
