Description
The RH850/C1M-Ax ASIL-C microcontroller is equipped with an RH850 Family G3MH CPU core, which operates at a frequency of 1x 240MHz for C1M-A1 and 2x 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 position-sensor output signals into digital angle data and a parallel embedded motor control unit (EMU3), providing a peripheral function set that is ideal for motor control in HEV/EV traction-inverter applications. In addition, C1M-A2 can simultaneously control two motors, e.g. for a starter/generator system.
