Description
Even though the RL78/G1M microcontroller has a small pin-count 20-pin package, it is an 8-bit general-purpose microcontroller equipped with real-time output terminals for motor drive. It has 120-degree energization control and can drive a BLDC motor. It is suitable for motor control for small home appliances, toys, office automation (OA) equipment, etc.
