STM32F071C8U7TR Features
This 32-bit ARM Cortex-M0 microcontroller delivers up to 48 MHz performance, providing responsive control for real-time tasks while keeping code size compact and power consumption low. It integrates 64 KB of embedded Flash for firmware storage and 16 KB of SRAM for data and buffers, supporting efficient execution of communication stacks and control loops. The device offers a versatile analog front end with a 12-bit ADC featuring up to 10 channels for sensor inputs, together with a dual 12-bit DAC that enables waveform generation, bias control, and audio/indicator tone synthesis without external converters.
Multiple timer resources enable precise PWM generation for motor and actuator control, event scheduling, and timebase creation. A DMA controller offloads data transfers between peripherals and memory, reducing CPU load and enhancing throughput in communication and sampling applications. Communication interfaces are comprehensive: SPI for high-speed serial peripherals, I2C for sensor and EEPROM connectivity, UART/USART for asynchronous links, LIN bus support for automotive and appliance networks, and integrated HDMI-CEC hardware for consumer electronics device interoperability. IrDA capability facilitates infrared communication for remote control and short-range data links.
The internal oscillator provides a convenient clock source with factory calibration, simplifying designs that do not require an external crystal and reducing BOM count. Operating over a wide temperature range of -40°C to +105°C, the device suits both consumer and industrial environments. Power management features and efficient peripheral design help minimize energy usage, and standard watchdogs and reset circuitry support robust operation even under supply disturbances.
