This application note is intended for system designers who require a hardware implementation overview of the low-power modes of the STM8S and STM8A product families. It shows how to use the STM8S and STM8A devices in these modes, describes how to take power consumption and wakeup time measurements, and gives results for such measurements.
This document serves as an application note for system designers requiring a hardware implementation overview of the low-power modes for the STM8S and STM8A product families. It details how to utilize these devices in various modes, describes methods for measuring power consumption and wakeup times, and presents the results of such measurements. Example firmware is provided to assist in implementing and measuring these parameters.
The devices require an operating voltage supply between 3 V and 5.5 V.
A capacitor of at least 470 nF must be connected between the Vcap pin and ground.
In Halt mode, the low-power voltage regulator (LPVR) is automatically used.
