M032 Series Microcontrollers

Nuvoton's NuMicro M032 series are 32-bit microcontrollers based on Arm Cortex-M0 CPUs with 32-bit hardware multipliers/dividers. They feature 1.8 V to 3.6 V operating voltage, 5 V I/O tolerance, and run up to 48/72 MHz within -40°C to +105°C.

The M032 series provides a comprehensive solution for the crystal-less USB applications needing 1.8 V interface connections with enhanced fast 2 MSPS conversion rate 12-bit ADC, comparators, and up to 24-ch 96/144 MHz PWM control. These provide a fast and precise data conversion for the voltage, current, and sensor data, then fast response control to the external device. Additionally, the M032 series provides peripherals, including universal serial control interfaces (USCI), that can be set as UART/SPI/I²C flexibly as up to ten sets of UART, four sets of SPI, four sets of I²C, and one-wire UART interfaces for data communication between primary and secondary devices.

The M032 series provides Flash size from 32 KB to 512 KB and SRAM size from 4 KB to 96 KB. Supported packages range from small form factor TSSOP20, TSSOP28, QFN33, and LQFP48 to LQFP64 and LQFP128 with pin-compatibility for different part numbers, making the system design and part changes easy.

Part numbers in the M032 series are enhanced with a crystal-less USB 2.0 full-speed device feature for USB-related applications.

For development, Nuvoton provides NuMaker evaluation boards and the Nuvoton Nu-Link debugger. Third-party IDE, such as Keil MDK, IAR EWARM, Eclipse IDE with GNU GCC compilers, and others, are supported.
