The NuMicro M471MD6AE is a 32-bit microcontroller based on Arm Cortex-M4F core, with DSP instruction set and single-precision floating-point unit (FPU), targeted for smart home appliance applications. For the growing requirement of the safety functions on the home appliance, the M471MD6AE provides certified Software Test Library (STL) and an application note for IEC60730-1 Class B Annex H. This certified STL can significantly reduce the development time and efforts to pass IEC60730-1 Class B certification for home appliances. The M471MD6AE runs up to 72 MHz, and features 2.5V to 5.5V wide operating voltage, -40°C to 105°C wide operating temperature, a variety of packages with wide pin pitch, and excellent high immunity characteristics by ESD HBM 8 KV and EFT 4.4 KV, which greatly meets the rigid requirements for stability, reliability and safety of home appliance systems.

As the new smart function added on home appliances, the M471MD6AE provides up to 64 KB Flash memory for code storage, 32 KB SRAM for run time operation. Data Flash could be configured in the 64 KB Flash memory to store parameters. Besides, a peripheral direct memory access (PDMA) is provided to reduce the data access overhead of CPU core to peripherals.

The M471MD6AE supports plenty of peripherals including up to 16 channels of 12-bit SAR ADC, up to 12 channels of 16-bit PWM, 1 set of USB 2.0 full speed Device/Host (crystal-less), 4 sets of UART, 1 set of SPI/I2S, 1 set of Quad-SPI, 2 sets of I²C, 1 set of ISO-7816, and a real-time clock (RTC).

Target Applications:

  • Washing Machine
  • Refrigerator
  • Air conditioner
  • PM2.5 detector
  • Other home appliances
