MCU-Energieaufnahme ohne Software regeln - von Horst Diewald
Bei Auswahl, Etablierung und Markterfolg eines Systems ist der Energiebedarf ein bedeutender Faktor. Doch der traditionelle Ansatz, die Energieeffizienz in Mikroampere oder µW/MHz anzugeben, greift heute nicht mehr. Das Powermanagement moderner Ultra-Low-Power-MCUs benötigt einen neuen Ansatz.

Ist ein Benchmark genug? - Energieverbrauch moderner Mikrocontroller-Systeme Juli 2017
Ein bedeutender Faktor für den Markterfolg ist der Energiebedarf eines Systems. Der traditionelle Ansatz, die Energieeffizienz in µA oder µW pro MHz anzugeben, greift heute nicht mehr. Energiespeichersysteme halten weder µA noch µW bereit, sondern Joule, also Energie. Was bedeutet das in der Praxis? Read more...

Energy consumption in modern microcontroller systems February 2017
Is there a strategy that can be applied to both IP-based and standard semiconductor products, that will allow device users to control energy consumption in a manner that is simple and reliable, that will give the user full visibility into operation, and that can maintain safe and secure conditions? Improved results can come with an increased degree of control of operating modes. Read more...

Part 1: A Benchmerk for ultra-low-power: ULPBENCH™-Core ProfileSeptember 2017

The conclusion - mainly stressed - is correct that low current in operating mode and sleep mode as well as shorter operating cycle lead to energy advantages. But there is no comparison possible with this very general conclusion; this can only be achieved with a benchmark. This means same software code for everybody. One code example gives the chance for a fair base for the test of 8-/16-/32-bit MCU/SoC architectures. The choice of the software and data has a profound impact on the result. Read more...

Part 2: ULP-Bench™ - core profile, EEMBC documents and MCU datasheets October 2017
In part 2 we look at data and documents based on public Benchmark data of the EEMBC organization. Relative to those Benchmark data datasheets and descriptions like app notes are sources to understand company data about energy demand of their products. Can the majority of engineers make proper decisions based upon the available documents without extensive research? Read more...

Part 3: The impact of operating temperature on energy consumption
The ULPBench-CP contains two (or even three) phases: operating mode (code execution) and sleep mode (RTC, clock). In addition, there are losses for the transition between modes. To estimate the impact of operating temperature without vendor data on energy consumption or battery life time, we evaluate existing public data from the ULPBench-CP. Read more...
