STM32F072CBU7TR Description

The STM32F072CBU7TR microcontroller features a high-performance ARM? Cortex?-M0 32-bit RISC CPU running at up to 48 MHz, high-speed embedded storage (up to 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and a wide variety of improved peripherals and I/Os. The standard communication interfaces that each device offers include two I2Cs, two SPI/I2S, one HDMI CEC, four USARTs, one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer, and an advanced-control PWM timer.

The STM32F072CBU7TR microcontroller may be powered by a 2.0 to 3.6 V supply and operates between the temperature ranges of -40 to +85 °C and -40 to +105 °C. Low-power applications can be designed thanks to a wide range of power-saving modes.

Devices for the STM32F072CBU7TR microcontroller are available in seven different packages, with pin counts ranging from 48 to 100. A die form is also available upon request. There are several sets of peripherals included depending on the device selected.
