GENERAL DESCRIPTION

The NuMicro

® M031/M032 series 32-bit microcontroller is based on Arm® Cortex® -M0 core with 32-bit

hardware multiplier/divider. It features 1.8 ~ 3.6 V operating voltage, 5 V I/O tolerant, and runs up to

48/72 MHz within -40°C ~105°C.

The M031/M032 series provides a solution for the applications that need 1.8 V low-voltage interface

connection with enhanced fast 2 MSPS conversion rate 12-bit ADC, comparators and up-to 24-ch

96/144 MHz PWM control. It supports a fast and precise data conversion for the voltage, current, and

sensor data, then fast response control to the external device. Additionally, the M031/M032 series also

provides plenty of peripherals including Universal Serial Control Interface(USCI) that can be set as

UART/SPI/I

2C flexibly, up to 10 sets of UART, 4 sets of SPI, 4 sets of I2C, and 1-wire UART interface

for data communication between master and slave devices.

The M031/M032 series provides Flash size from 16 Kbytes to 512 Kbytes, SRAM size from 2 Kbytes

to 96 Kbytes. Supported packages from small form factor TSSOP 20-pin, TSSOP 28-pin, QFN 33-pin,

LQFP 48-pin to LQFP 64-pin and LQFP 128-pin with pin-compatible for different part numbers makes

the system design and parts change easily.

Part Numbers with the M032 series are all based on the M031 series and enhanced with the crystal-

less USB 2.0 full-speed device feature for USB related applications.

For the development, Nuvoton provides the NuMaker-PFM evaluation board and Nuvoton Nu-Link

debugger. The 3

rd Party IDE such as Keil® MDK, IAR EWArm, Eclippse IDE with GNU GCC compilers

are also supported.
