This MCU comes in a 48-UFQFN exposed-pad package (7x7 mm body). The 37 I/O lines are accessible on the perimeter, which keeps routing manageable on a two-layer board.
The base product number is STM32F071, and the STM32F0 family has broad distribution support, so second-sourcing through a pin-compatible STM32F0 variant with matching Flash and RAM is feasible if supply tightens.
Yes, the 48 MHz Cortex-M0 core, PWM timers, and 13-channel 12-bit ADC are sufficient for sensorless or low-end field-oriented control of small motors. The 16 KB SRAM limits the lookup-table size, so vector control with full observer may need a larger-RAM sibling.
Within the STM32F0 family, the STM32F070 and STM32F072 series share the same 48-pin UFQFN footprint and peripheral set, with differences in Flash and RAM density. The STM32F072 adds a USB 2.0 full-speed interface. For a direct drop-in with identical memory, the STM32F071CBT6 (LQFP-48) is pin-compatible but uses a different package body.
