M071MD2AE

The NuMicro® M071MD2AE series is a 32-bit microcontroller based on Arm Cortex®-M0 core targeted for smart home appliance applications. It offers up to 50 MHz CPU frequency, 68 KB Flash memory for code storage, 8 KB SRAM for runtime operation. Additionally, in response to the code security requirements, the M071MD2AE series integrates flash security lock to provide a secure code execution area to protect the developer's intellectual property. The M071MD2AE 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 4 KB Loader ROM (LDROM) supports firmware updates through the Firmware Over-The-Air (FOTA) process.

The M071MD2AE 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, 12 channels of 16-bit 144 MHz high-speed PWM for precise control, 4 sets of UART, 1 set of SPI, 1 set of I²C. The M071MD2AE series also provides rich analog peripherals including 8 channels of 12-bit ADC.
