2. Describe

STM32F072x8/xB microcontrollers include a high-performance Arm®Cortex®-M0 32-bit RISC core running at up to 48 MHz, high-speed embedded memory (up to 128 KB Flash and 16 KB SRAM), and a wide range of enhanced peripherals and I/O. All devices provide standard communication interfaces (two I2C, two SPI/I2S, one HDMI CEC and four USART), one USB full speed device (no crystal), one CAN, one 12-bit ADC, one 12-bit DAC two channel, seven 16-bit timers, one 32-bit timer and one advanced control PWM timer. The STM32F072x8/xB microcontrollers operate in the temperature range -40 to +85 °C and -40 to +105 °C with a supply voltage of 2.0 to 3.6 V. A comprehensive set of power-saving modes allows the design of low-power applications. The STM32F072x8/xB microcontrollers are available in seven different packages, from 48-pin to 100-pin, and are also available in die form upon request. Depending on the device selected, different sets of peripherals are included. These features make the STM32F072x8/xB microcontrollers suitable for a wide range of applications such as application control and user interface, handheld devices, A/V receivers and digital TVs, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters appliances, printers, scanners, alarm systems, video intercoms and HVAC.

3. Pin configuration

4. Analog to digital converter

The 12-bit analog-to-digital converter has up to 16 external and 3 internal (temperature sensor, voltage reference, VBAT voltage measurement) channels and performs conversions in single shot or scan mode. In scan mode, an automatic conversion is performed on a selected set of analog inputs. The ADC can be serviced by the DMA controller. An analog watchdog function allows very precise monitoring of the transition voltage of one, some or all selected channels. An interrupt is generated when the converted voltage exceeds the programmed threshold.

5. Digital to analog converter

    1. 8-bit or 12-bit monotonic output

    2. Left or right data alignment in 12-bit mode

    3. Synchronous update capability

    4. Noise wave generation

    5. Triangle wave generation

    6. Independent or simultaneous conversion of dual DAC channels

    7. DMA capability per channel

    8. External trigger for conversion
