Product details

48 MHz Cortex-M0 with 128 KB Flash — the BOM-fit tier

This is the mid-density, mid-pin-count sweet spot in the F0 line — enough memory for a real application stack without the cost or footprint of the larger F1 or F4 parts.

Peripheral set — CAN, USB, and analog on one die

The DMA engine keeps the CPU from stalling on peripheral transfers, which matters when the 48 MHz core is servicing a USB or CAN frame.

For a production BOM, this is the safe pick — you are not chasing surplus inventory or qualifying a replacement mid-run. The base product number is STM32F072, so any PCN or errata updates apply across the family.

Frequently asked questions

What is the difference between STM32F072CBT6 and STM32F072RBT6?

The two parts share the same core, memory, and peripheral set. The difference is the package and pin count: the CBT6 comes in a 48-pin LQFP with 37 I/Os, while the RBT6 is a 64-pin LQFP with more I/Os. Choose the CBT6 when 37 I/Os are enough and you want the smaller footprint.
