48 MHz Cortex-M0 with 128 KB Flash — mid-range STM32F0 for cost-sensitive control
It packs 87 general-purpose I/Os into a compact 100-UFBGA (7x7 mm) package, making it a fit for space-constrained industrial control, sensor aggregation, and human-machine interface applications where cost per pin matters.
100-UFBGA footprint — layout and rework considerations
The 100-UFBGA (7x7 mm) package uses a fine-pitch ball array that demands a clean PCB design with via-in-pad or microvia capability for routing the 87 I/Os. The small body size helps in dense boards but makes manual rework difficult — a hot-air rework station with a pre-heater and a stencil for solder paste is recommended for prototyping. The package is surface mount only, and the tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel, which affects pick-and-place feeder setup.
STMicroelectronics lists the STM32F071VBH6 as Active (current production). The base product number STM32F071 covers a range of Flash and package variants, providing some supply flexibility within the family.
