Working Principle
STM8 16-bit core with 3-stage pipeline executes instructions at up to 16 MHz. Multiple low-power modes (wait, active-halt, halt) reduce current to sub-µA range. Peripheral clock gating minimizes active power. Autonomous peripherals (RTC, comparator, ADC) operate in low-power modes for wake-on-event functionality.
Applications
- Smart meter (water/gas)
- Wearable sensor node
- Remote control
- Energy harvesting system
