Application note
Introducing the low-power concept in automotive applications using
the STM8AL board of the STM8A-DISCOVERY
Introduction
This application note illustrates the power consumption benefits of the STM8AL devices
included with the STM8A-DISCOVERY. This new family of devices has been designed to
comply with AEC-Q100 rev G. automotive requirements and offer high performance with
ultra-low power management capabilities.
The STM8AL board of the STM8A-DISCOVERY has a built-in I_DD measurement feature that
is used to demonstrate the efficiency of the low power modes of the STM8AL devices.
This application does not require any additional hardware or software. Once the STM8AL
board is powered-up through a USB cable connected to the host PC with the USER1 button
pressed, the user can access the low power software resources of the standard
demonstration package.
This low-power software example comes preloaded with your STM8A-DISCOVERY, but is
accessible when the USER1 or USER2 buttons are pressed during the board’s power
supply sequence.
