Product details

The 48 MHz clock lets it handle a few hundred microseconds of interrupt latency for motor commutation or digital power loops, while the Cortex-M0 keeps the code density tight for the flash budget.

The 39 I/O pins give enough headroom for a keypad, a few encoder inputs, and a serial debug link. That covers analog feedback from current-sense resistors or thermistors without an external ADC.

Package and thermal: 48-UFQFN with exposed pad

The exposed-pad package (supplier device package 48-UFQFPN, 7x7 mm) is a compact surface-mount option for space-constrained PCBs.

Frequently asked questions

Is STM32F051C8U7TR compatible with STM32F051C8T6?

The STM32F051C8T6 uses an LQFP-48 package, while this part uses a 48-UFQFN exposed-pad package. They are not footprint-compatible — the UFQFN has a different pad layout and thermal pad. The core, memory, and peripheral set are identical, so firmware can be reused with a board respin.
