A bootloader, a communication stack (say, I²C + UART), and a state machine for a simple sensor node will fit. The 256-byte EEPROM is useful for calibration constants or fault logs that survive power loss. The STM8L151K3U6 carries an EOL-hot lifecycle status. That means ST has announced end-of-life for this specific order code, and the last-time-buy window is either closed or closing. New production from the factory is not guaranteed. ## Peripherals and integration On-chip peripherals include a 12-bit ADC with 23 channels, multiple timers with PWM, a watchdog timer, brown-out reset, power-on reset, and a DMA controller. The internal oscillator saves an external crystal for many applications.","metaTitle":"ST STM8L151K3U6 8-bit MCU, 16 MHz, 8 KB Flash, 32-UFQFPN","metaDescription":"STMicroelectronics STM8L151K3U6 8-bit MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 30 I/O, -40 to 85°C.
