The RH850/C1M-Ax microcontroller is equipped with an RH850 Family G3MH (C1M-A2 is dual)CPU core, which operates at a frequency of 240MHz for C1M-A1 and 320MHz for C1M-A2, 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, C1M-A2 can simultaneously control two motors.
