NuMicro® M0A23 Series Microcontroller

Nuvoton's NuMicro M0A23 series 32-bit microcontroller with an Arm Cortex-M0 core is available in a compact package. It features a highly ‎flexible digital pin function assignment, rich analog peripherals, -40°C to +125°C operating temperature range, 2.4 V ~ 5.5 V operating ‎voltage, CAN 2.0B, and LIN interface for robust communication. The NuMicro M0A23 series targets high operating temperature ‎applications, such as 24 GHz mmWave radar, battery management systems (BMS), car lighting, electric window lifters, and power ‎seats‎.

The NuMicro M0A23 series are available in SSOP20 and TSSOP28 packages with analog and digital functions suitable for small form ‎factor applications. The SSOP20 provides up to 18 IO pins, and the TSSOP28 provides up to 26 IO pins. Each IO pin of the M0A23 ‎series can be assigned to digital peripherals such as UART, SPI, and PWM. The M0A23 series provides rich analog functions, ‎including 17-ch 12-bit 500 kSPS ADC, one set of 5-bit DAC, and two sets of analog comparators (ACMP) in both the SSOP20 and ‎TSSOP28 packages. It provides a low voltage reset (LVR) and brown-out detector (BOD) to ensure system safety.

The NuMicro M0A23 series runs up to 48 MHz and supports a hardware divider. It provides 32 KB of Flash memory, 4 KB of SRAM, ‎and 2 KB of LDROM for an in-system programming (ISP) feature for easy firmware updates. It is equipped with peripherals including ‎up to four 32-bit timers, 6-ch 16-bit PWM generators, one CAN 2.0B controller, two sets of LIN functions, 5-ch PDMA, two sets of UART ‎with one-wire mode, IrDA, and RS485 functions. The M0A23 series provides two sets of universal serial control interfaces (USCI) that ‎can be configured as UART, SPI, or I²C.
