Nuvoton Technology launches a new high flexibility 125°C NuMicro® M0A21/M0A23 series microcontroller with multiple functions and rich-analog in compact packages

Hsinchu, Taiwan - 2021/04/22 - NuMicro® M0A21/M0A23 series is a 32-bit Arm® Cortex®-M0 high-performance microcontroller for automotive and industrial applications. NuMicro M0A21/M0A23 series provides rich analog and digital peripherals in SSOP20, TSSOP28 packages, especially suitable for small form factor applications. M0A21/M0A23 series offers up to 18 IO pins in SSOP20 and up to 26 IO pins in TSSOP28 with optimized pin functions.

NuMicro M0A21/M0A23 runs up to 48 MHz at up to 125°C operating temperature, under 2.4V to 5.5V wide operating voltage with high immunity capability.

NuMicro M0A21/M0A23 series IO pins can be assigned to multiple digital functions, including CAN 2.0B interface, UART, I2C, SPI, Timer, LIN, PWM. Additionally, it provides up to 17 channels of 12-bit ADC, 2 set comparators, and 5-bit DAC to reduce components and the PCB size of end products. NuMicro M0A21/M0A23 could be suitable for the battery management system (BMS), automotive ultrasonic radar control, automotive lighting, automotive body control, and power applications.

NuMicro M0A21/M0A23 series features 32 KB flash, 4 KB SRAM, rich peripheral including four sets of 32-bit timers, 6-ch of PWM, 1 set of CAN 2.0B interface supported CAN bootloader firmware update function, two sets of LIN, five sets of PDMA, two sets of UART support single-wire transmission, infrared and RS485 functions. 2 sets of Nuvoton patented Universal Serial Communication Interface (USCI) can be flexibly defined as UART, SPI or I2C.

Multiple IDEs are supported, including the Keil MDK Nuvoton Edition, IAR EWARM, and NuEclipse. Among the IDEs, the Keil MDK Nuvoton Edition (for NuMicro Cortex-M0 family) and NuEclipse are free-to-use. Besides, easy-to-use software development tools including PinView, PinConfig to speed up the development time for time to market.
