STMicroelectronics is winding down support; the part remains available for existing production runs through last-time-buy windows and surplus channels, but it should not be selected for new board designs. For a new project, look at the current STM8A family members in the same 32-VFQFN footprint — the base product number STM8 covers the active siblings. ## 32-VFQFN exposed pad — layout and rework notes The package is a 32-VFQFN with an exposed thermal pad (5x5 mm). The pad needs a solid via-stitch to the ground plane to pull heat out — without it, junction temperature climbs fast above 85°C ambient.","metaTitle":"STM8AF6246UAX 8-bit MCU, 16 MHz, 16 KB Flash, NRND","metaDescription":"STMicroelectronics STM8AF6246UAX 8-bit MCU, 16 MHz core, 16 KB Flash, 2 KB RAM, 512 B EEPROM, industrial temp -40°C to 85°C.
