M471R1E6AE Datasheet | Nuvoton Technology

DESCRIPTION The Nu Micro® M471M/M471R1/M471S series 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 M471M/M471R1/M471S series 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 M471M/M471R1/M471S series 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 meet the rigid requirements for stability, reliability and safety of home appliance systems. As the new smart function added on home appliances, the M471M/M471R1/M471S series provides up to 128 KB Flash memory for code storage, 32 KB SRAM for run time operation. Data Flash could be configured in the 128 KB Flash memory to store parameters. In order to reduce the data access overhead of CPU core to peripherals, a peripheral direct memory access (PDMA) is provided. The M471M/M471R1/M471S series supports plenty of peripherals including up to 16 channels of 12bit 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). For the development, Nuvoton provides the Nu Maker-M471R1 evaluation board, and Nuvoton Nu-Link debugger. The 3rd Party IDE such as Keil MDK, IAR EWARM, Eclippse IDE with GNU GCC pilers are also supported.
