The 7-channel 10-bit ADC provides enough resolution for analog sensor inputs like temperature, current, or position feedback. The 25 I/O pins in the 32-LQFP package offer a balanced pin count for compact PCB layouts.","metaTitle":"ST STM8S105K4T3C 8-bit MCU, 16 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM8S105K4T3C 8-bit MCU: 16 MHz core, 16 KB Flash, 2K x 8 RAM, 1K x 8 EEPROM, 7x10b ADC, -40 to 125°C, LQFP-32.
