Nuvoton_M031_Series_Diagram

Nuvoton NuMicro® M032 series is 32-bit microcontrollers based on Arm® Cortex®-M0 CPU with 32-bit hardware multiplier/divider. It features 1.8V ~ 3.6V operating voltage, 5V I/O tolerant, running up to 48/72 MHz within - 40~105 ℃ .

M032 series provides a comprehensive solution for the Crystal-less USB applications that need 1.8V 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, providing a fast and precise data conversion for the voltage, current, and sensor data, then fast response control to the external device. Additionally, M032 series also provides plenty of peripherals included Universal Serial Control Interface ( USCI ) can be set as UART / SPI / I²C flexibly, up to 10 sets of UART , 4 sets of SPI , 4 set I²C , 1-wire UART interface for data communication between master and slave devices.

M032 series provides Flash size from 32 KB to 512 KB , SRAM size from 4 KB to 96 KB . Supported packages from small form factor TSSOP20, TSSOP28, QFN33, LQFP48 to LQFP 64 and LQFP128 with pin-compatible for different part number makes the system design and change parts easily.

Part Numbers with M032 series are enhanced with crystal-less USB 2.0 full-speed device feature for USB related application.

For the development, Nuvoton provides the NuMaker evaluation boards and Nuvoton Nu-Link debugger. 3rd Party IDE is supported such as Keil MDK, IAR EWARM, Eclippse IDE with GNU GCC compilers etc.
