The STMicroelectronics STM8AL3L68TAY is an 8-bit microcontroller from the STM8A series, built around the STM8 core and clocked at 16 MHz. That many ADC inputs reduce the need for an external multiplexer in multi-sensor applications — think motor-current sensing, temperature monitoring, or analog front-end consolidation.
