Update: 28 September, 2023
The purpose of this application note is to explain how to keep real-time information on a STM8S or STM8A device maintained in low power mode. Only simple solutions which do not require any additional hardware are described in this application note. They are suitable for applications which do not need a very accurate real- time measurement. To benefit fully from the information in this application note, the user should be familiar with the STM8S and STM8A microcontroller architecture and with the basics of C language. For further information on the STM8S and STM8A family features, pinout and electrical characteristics, please refer to the STM8S and STM8A datasheets. An STM8S and STM8A firmware package is delivered with this application note. It contains the complete C source code of an example described in this application note, so that the user can compile, link or modify it as necessary. This document and its associated firmware package, are written to accompany the STM8S and STM8A firmware library. It includes many examples describing how to use the STM8S and STM8A timers, the clock system, the beeper and the auto-wakeup unit mentioned in this application note.
