It has 8 KB Flash, 1 KB RAM, and 640 bytes EEPROM, operating from 2.95 V to 5.5 V. The 32-LQFP package provides 28 I/O lines. The 16 MHz clock rate is enough for a 10 ms control loop with sensor polling and a UART transaction; for faster PWM update rates or multiple serial ports running simultaneously, check the instruction-cycle budget against your interrupt latency. ## Memory sizing — Flash, RAM, and EEPROM 8 KB of Flash holds a bootloader and main loop. The 1 KB RAM handles buffers and stack. The 640-byte EEPROM stores calibration constants or fault logs.","metaTitle":"ST STM8S103K3T6C 8-bit MCU, 16 MHz, 8 KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8S103K3T6C 8-bit MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, -40 to 85°C, 32-LQFP.
