48 MHz Cortex-M0 with USB and CAN in a 4×4 mm package
It packs a USB 2.0 full-speed device controller and a CAN 2.0B interface into a 28-pin 4×4 mm UFQFPN package — an unusual peripheral density for this footprint that saves board space in space-constrained designs like sensor nodes, compact motor drives, and portable instrumentation.
Memory and peripheral fit check
The 6 KB SRAM handles two 512-byte USB buffers and a modest data array, but any heavy frame buffering or large lookup tables will push you to the external memory or a higher-density sibling in the STM32F0 series. The 13-channel 12-bit ADC samples at up to 1 µs per conversion — adequate for current-sense feedback in a BLDC motor controller or reading a few analog sensors, but not for high-speed data acquisition.
Industrial temperature and active lifecycle
The lifecycle status is Active, meaning ST continues to manufacture it with no announced end-of-life — no LTB risk for production programs starting today.
