Smart Home Audio(325)



Nuvoton NuMicro M031SIAAE is low-voltage operation MCU based on Arm® Cortex®-M0 core with 32-bit hardware multiplier/divider. Operating frequency up to 72 MHz with 1.8V ~ 3.6V operating voltage, equipped 512 KB Flash and 96 KB SRAM.

The M031SIAAE BSP (Board Support Package) comes with licensed industrial leading emWin embedded GUI library, which contains emWin library, samples, tools and documents.

M031SIAAE embedded an extra SPROM (Security Protection ROM), providing a secure code execution area to protect the intelligent property of developers.

With its special designed such as 24-ch 96 MHz PWM providing fast response control to the external devices, 2 MSPS ADC providing a fast and precise analog to digital data conversion for sensing voltage and current which is very suitable for gaming application. Additionally, M031SIAAE provide high speed communication interface included 24 MHz SPI for high speed sensor device communication, 7.2 MHz UART with 1-wire function for encrypted communication target sensing/control devices and consumer device.

M031SIAAE also provides plenty of peripherals included 9-ch PDMA, 2 set Universal Serial Control Interface(USCI) which can be configure as UART, SPI or I²C, 8 set UART, 2 set I²C, 1 set SPI/I²S, 1 set Qual SPI, 16-ch 12-bit 2 MSPS ADCs for various application demand. And it can operate in a wide temperature range from -40°C to 105°C.
