It is not a number-cruncher for DSP or heavy protocol stacks; the 8-bit architecture and 2 KB RAM limit the buffer depth for things like USB or Ethernet. For a LIN slave node, a simple HMI keypad controller, or a fan-speed PWM driver, the speed is adequate and the power draw stays low. ## Memory sizing for firmware and data The 1 KB EEPROM lets you store calibration constants, serial numbers, or fault logs without wearing the Flash. The 2 KB RAM is tight for large buffers; if your design needs a big UART FIFO or a frame buffer, check the memory map early.","metaTitle":"ST STM8S105C6T3TR 8-bit MCU, 16 MHz, 32 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8S105C6T3TR 8-bit MCU: 16 MHz core, 32 KB Flash, 2 KB RAM, 1 KB EEPROM, -40 to 125 °C, 48-LQFP.
