The STM8L151K6U6 is an 8-bit MCU from ST's STM8L EnergyLite series, built around the STM8 core running at 16 MHz. The 22-channel 12-bit ADC and single 12-bit DAC cover analog sensor acquisition and analog output generation on one chip, which saves board space in battery-powered or industrial control designs.
The 30 I/O lines in a 5x5 mm 32-UFQFPN package with exposed pad help with thermal dissipation when driving moderate loads.
Peripherals and connectivity — what hooks up
On the communication side, the MCU includes I2C, SPI, UART/USART, and IrDA interfaces — enough for typical sensor buses, serial displays, or wireless module links.
