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 ~ 3.6V operating voltage, 5V 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 1.8V 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. 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
2
Interface(USCI) that can be set as UART/SPI/I C flexibly, up to 10 sets of UART, 4 sets of
2
2
SPI/I S, 4 sets of I C, 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
rd
debugger. The 3 Party IDE such as Keil MDK, IAR EWARM, Eclippse IDE with GNU GCC
compilers are also supported.
