Overview
The STM8L162M8T6 is a high-density, ultra-low-power 8-bit microcontroller from STMicroelectronics. It features an enhanced STM8 CPU core, providing 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 designed 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, low-power low-voltage single-supply program Flash memory, and a wide range of enhanced I/Os and peripherals. These include a 12-bit ADC, two DACs, two comparators, a real-time clock, AES encryption, and various communication interfaces such as SPI, I2C, and USARTs.
