NuMicro® M0A21/M0A23 32-bit Microcontrollers

Nuvoton NuMicro® M0A21/M0A23 32-bit Microcontrollers are based on the Arm® Cortex®-M0 core with a highly flexible digital pin function assignment in a compact package. The M0A21/M0A23 features a 40°C to 125°C operating temperature, 2.4V to 5.5V voltage, CAN 2.0B, and LIN interface for powerful communication. The MCUs target rugged and high operating temperature applications, such as 24GHz mmWave radar, Battery Management Systems (BMS), car lighting, electric window lifters, and power seats.
