The STM32F072CBU7TR includes USB, CAN, HDMI-CEC, I²C, SPI, USART, LIN, and IrDA connectivity, and 37 general-purpose I/Os. The 48-UFQFPN exposed-pad package (7x7 mm) keeps the footprint tight and helps pull heat out of the die in enclosed assemblies.
Industrial temperature grade and environment
The exposed pad on the 48-UFQFPN package drops junction temperature by conducting through a PCB thermal via array — worth populating if the part runs continuous ADC conversions or PWM at high duty cycles in a 85°C+ ambient.
STMicroelectronics lists the STM32F072CBU7TR as Active.
What the 48 MHz and memory mean in practice
The Cortex-M0 core at 48 MHz is a throughput tier for cost-sensitive control: sensor polling, brushless-DC commutation loops, USB virtual COM port bridging, or CAN gateway tasks. 128 KB of Flash holds a moderate firmware image with a bootloader and a few protocol stacks; 16 KB SRAM leaves room for a couple of 1 KB buffers plus stack and heap. If the application needs a USB descriptor table plus a CAN message queue, check the RAM budget early — the 16 KB fills faster than you expect.
This part integrates USB (device/Host/OTG), CAN, HDMI-CEC, I²C, SPI, USART, LIN, and IrDA — enough serial interfaces to talk to a sensor array, a display, a motor controller, and a fieldbus gateway without external UART expanders or USB bridge chips. DMA and I²S are on board for streaming audio or moving ADC results without CPU overhead.
