Top 5 low power MCUs - secure high processor performance per watt

In your electronic product design's power consumption budget, the share of power consumed by microcontrorller is higher and important, then naturally you look for selecting a microcontroller consuming as low power as possible without compromising on performance. Example, if you're designing a health monitoring device running on battery, selecting a lowest power consuming microcontroller is necessary. So you may finally start hunting for low-power micrcontrollers in the market. In some applications microcontroller need to process the data at normal to full capacity only for a short period of time, where as in some cases microcontroller churns out a lot of data processing 90% of the time, switching to no work/sleep mode for a very less percentage of its operation time. So your selection of microcontroller chip depend on these design requirements. The key technology trends in microcontrollers to save power includes, multiple power modes of operation, wide operating voltage and ability to operate at very low voltage and also the time microcontrollers required to shift from one mode to other mode. Some of the microcontrollers may consume more power but provide a lot of functions internally in the chip, so that you can save the board from using those external components and the power consumption of those parts. To save your time, and also to keep you more informed...
