What this 8-bit MCU brings to a control-board BOM
The STMicroelectronics STM8AF6246TASSSY is an 8-bit microcontroller from the STM8A series, built around the STM8A core and clocked at 16 MHz. It carries 16 KB of Flash program memory, 2K x 8 of RAM, and 512 x 8 of EEPROM — enough for moderate embedded control firmware with calibration or configuration data stored on-chip.
That means ST still manufactures it for existing production, but they are not targeting it for new socket wins. For a new design, the safer call is to pick a current STM8A variant with compatible memory and pinout.
The 7-channel 10-bit ADC handles analog inputs like temperature or position sensors without an external converter.
Housed in a 32-LQFP (7x7 mm) with 25 I/O lines, this is a surface-mount package that reworks cleanly with hot air if the pad layout follows the recommended footprint.
