The NuMicro M471KI8AE 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 M471KI8AE 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 M471KI8AE runs up to 120 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 M471KI8AE provides up to 512 KB dual-bank of Flash memory for code storage, 64 KB SRAM for run time operation and 32 KB independent Data Flash for parameters. The dual bank design of 512 KB Flash memory supports the Firmware update through the Over-The-Air (FOTA) process. Additionally, in response to the code security requirements, the M471KI8AE supports Execute-Only Memory (XOM) function to protect confidential program code information from being stolen in the run-time. Finally, the 32 KB independent Data Flash provides a 256 Bytes page erasing unit to make the parameter data update and access more efficiently. Besides, a peripheral direct memory access (PDMA) is provided to reduce the data access overhead of CPU core to peripherals.

The M471KI8AE supports plenty of peripherals, including a Customize IR receiver (CIR) to communicate with remote controller, up to 24 channels of 16-bit PWM, 6 sets of UART, 2 sets of SPI/I²S, 2 sets of I²C, and a real-time clock (RTC).

The M471KI8AE also provides rich analog peripherals including 2 sets of analog comparators, up to 24 channels of 12-bit SAR ADC, and 1 channel of 8-bit DAC. The M471KI8AE also integrates a pseudo random number generator (PRNG) to support the requirement for encryption and decryption of smart home appliances.
