M071R1E3AE

The NuMicro® M071R1E3AE series is a 32-bit microcontroller based on Arm Cortex®-M0 core targeted for smart home appliance applications. It offers up to 72 MHz CPU frequency, 128 KB Flash memory for code storage, 16 KB SRAM for runtime operation and configurable Data Flash memory for parameters. Additionally, in response to the code security requirements, the M071R1E3AE series integrates flash security lock to provide a secure code execution area to protect the developer's intellectual property. The M071R1E3AE series also supports online updates using In-System Programmer (ISP), In-Circuit Programmer (ICP) and In-Application Programmer (IAP). The In-System Programmer (ISP) with 8 KB Loader ROM (LDROM) supports firmware updates through the Firmware Over-The-Air (FOTA) process. Besides, a Peripheral Direct Memory Access (PDMA) is provided to reduce the data access overhead of CPU core to peripherals.

The M071R1E3AE series supports plenty of peripherals, including one built-in temperature sensor with 1°C resolution, adjustable VDDIO pins to meet a wide voltage range from 1.8V to 5.5V, 6 channels of 16-bit 144 MHz high-speed PWM for precise control, 3 sets of UART, 2 set of SPI, 2 sets of I²C, and a Real-Time Clock (RTC). The M071R1E3AE series also provides rich analog peripherals including 12 channels of 12-bit ADC and integrates one set of USB 2.0 full speed Device with on-chip PHY which supports crystal-less in device mode.

Target Application:

• Main control of White Goods
• Main control of Smart Home Appliances
• Industrial control
