Hardware manufacturer Nuvoton has debuted two motor control units, the KM1M4BF Series MCU and the KM1M7AF Series MCU, according to a press release.

KM1M4BF

The KM1M4BF series MCUs are designed for manufactured goods including white goods, air conditioning, e-bikes and equivalent EV motors. Powered by an Arm® Cortex®-M4F CPU operating up to 120MHz, with integrated Flash and SRAM, it supports a wide operating voltage of 2.9-5.5V and wide operating temperature of -40 degrees Celsius ~ +110 degrees Celcius.

KM1M7AF

The KM1M7AF series MCU is designed for high voltage power supply applications such as EV charging, and energy storage, where it can control primary PFC (AC/DC) and secondary LLC (DC/DC) from a single MCU, reducing component count and platform cost. It provides high speed, highly accurate feedback control via high-speed ADC (2Msps) and high resolution PWM (208ps). For heat pumps and commercial-grade air conditioning, it can control up to two motors and provides state-of-the-art thee-phase interleaved PFC simultaneously.

Powered by an Arm Cortex-M7 core operating up to 160MHz with integrated Flash and SRAM, it supports a wide operating voltage of 3.5-5.5V and wide operating temperature of -40 degrees Celsius ~ +110 degrees Celsius.
