STM8S105C6T6 general-purpose MCU IC 8-Bit 16MHz 32KB (32K x 8) FLASH
The STM8S105C6T6 is an entry-level 8-bit general-purpose MCU from STMicroelectronics' STM8S Access Line, housed in a 48-LQFP 7x7 mm surface-mount package, designed for cost-sensitive low-to-medium complexity embedded control systems. Built on the advanced 16 MHz STM8 Harvard architecture with 3-stage pipeline, this industrial-grade MCU integrates 32 KB embedded Flash, 1 KB true data EEPROM, 2 KB RAM, and operates stably across the full -40 °C to 85 °C temperature range with a 2.95 V to 5.5 V wide power supply.
It delivers a set of highly optimized practical features that outperform most competing 8-bit MCUs in its class, including 10-bit 10-channel ADC, 3 flexible 16-bit timers with capture/compare and PWM output, native UART, SPI and I2C communication peripherals, 300K-cycle EEPROM endurance with 20-year guaranteed data retention at 55 °C, integrated low-power crystal oscillator and internal RC clock sources, plus comprehensive clock security and reset protection mechanisms to ensure robust operation in harsh industrial environments.
