Overview
The STM8L151G2U6 is an ultra-low-power 8-bit microcontroller from STMicroelectronics, part of the STM8L151x2/3 family. It features an enhanced STM8 CPU core that provides increased processing power of up to 16 MIPS at 16 MHz, while maintaining the advantages of a CISC architecture with improved code density and a 24-bit linear addressing space. This microcontroller is optimized for low-power operations and includes an integrated debug module with a hardware interface (SWIM) for non-intrusive in-application debugging and ultrafast Flash programming.
The device incorporates embedded data EEPROM and low-power, low-voltage single-supply program Flash memory. It also includes a range of enhanced I/Os and peripherals, such as a 12-bit ADC, two comparators, a real-time clock, two 16-bit timers, one 8-bit timer, and standard communication interfaces like SPI, I2C, and USART.
