The STM32F072xx microcontrollers incorporate the high-performance ARM Cortex™-M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (up to 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (two I2Cs, two SPIs/I2S, one HDMI CEC and four USARTs), one USB Full speed device (crystal-less), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven general-purpose 16-bit timers, a 32-bit timer and an advanced-control PWM timer.

The STM32F072xx microcontrollers operate in the -40 to +85 ℃ and -40 to +105 ℃ temperature ranges from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.

The STM32F072xx microcontrollers include devices in six different packages ranging from 48 pins to 100 pins with a die form also available upon request. Depending on the device chosen, different sets of peripherals are included. The description below provides an overview of the complete range of STM32F072xx peripherals proposed.

These features make the STM32F072xx microcontrollers suitable for a wide range of applications such as application control and user interfaces, handheld equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
