Conclusion

The STM8AL family of devices offers new opportunities for the automotive world and

combines both a high performance core and an ultra-low power management mechanism.

As more and more vehicles are being equipped with electronic components and since

microcontrollers are much more present in automotive applications, this induces additional

energy constraints, in particular for electrical vehicles. Controlling and reducing the global

power consumption of all these electronic elements is a new challenge for today’s and

tomorrow's automotive developments. The STM8AL family can be a solution to drastically

decrease the power consumption of a standard automotive system.

The example discussed in this document allows you to evaluate the current consumption of

the STM8AL microcontroller in various operating conditions and to demonstrate its low-

power capabilities by directly providing the consumption value to the STM8AL board LCD

panel.

More generally, STM8A-DISCOVERY provides a very low-cost environment that can be

used for additional automotive development projects. The example shown here can be a

useful starting point that can easily be expanded to investigate other aspects of the user's

target application, especially when lowering consumption is of consideration.
