M370 Group
The M370 Group of microcontrollers contain a Vector Engine (VE) that implements the common computation functionality for
motor vector control. Additionally, the VE is closely coupled with a three-phase PWM timer and a 12-bit AD converter for
motor current sensing. The M370 Group are designed to improve motor control efficiency while reducing software workload.
The M370 Group operate with a single 5-V supply and provide analog comparators and amplifiers to help cut system costs.
