STM32G031G8U6

STM32G031G8U6 is the tray UFQFPN-28 ordering code for the STMicroelectronics STM32G031 microcontroller, listed as Active on the maker’s eStore page for this exact code (the U6 suffix is the tray form; the tape-and-reel U6TR form carries the same Active status). It is a mainstream Arm Cortex-M0+ device at 64 MHz with 64 KB of Flash and 8 KB of SRAM, on a 1.7 V to 3.6 V supply, in a 4 × 4 mm UFQFPN-28 package, industrial grade. The selection point is the top memory step of the G031 line in the 28-pin package: the full 64 KB of Flash of the family in the smallest pin count, for cost-driven appliance, consumer and industrial nodes that outgrew the smaller memory steps. Selection advice: the package letter and the memory step are both carried in the code - G8 fixes this UFQFPN-28 body and the 64 KB step, and same-family codes in other packages are not footprint substitutes. Parameters verified against the ST eStore listing for this exact code and the STM32G031 family documentation.
