Power means everything for your Internet of Things design
Ultra-low power is crucial if you want to win in the IoT market. A typical IoT end-node needs to operate for years on the same small-form-factor battery. How do you know if you’re designing an app that isn’t as energy efficient as it could be?

If you use Kinetis MCUs, you can estimate how much energy your design requires with the Power Estimation Tool. With its easy-to-use graphical interface, download this free tool so you can:

  • Quickly estimate and optimize your system’s power consumption
  • Design for efficient use of energy – a must for Internet of Things applications
  • Compare various Kinetis MCUs to see which one is the best for your design

Get started: How to configure, estimate and optimize for power consumption

Getting started is a snap. You can read through the documentation provided. Just click on the help>documentation

You can also learn about it by watching our Getting Started Video.

Here’s a summary of how to get started with the tool.

  1. Go to the Kinetis Power Estimation Tool page.
  2. Download the Kinetis Power estimation Tool.
    Install the tool and select the MCU of your choice.
  3. Get familiar with the interface.
    The power estimation tool includes various options and views, from MCU and battery selection to consumption and discharge graphs. The next steps focuses on some of the bolded features in the image below so that you can easily get started with this tool.
  4. Configure the battery as per your need.
    Once you choose the MCU of your choice, you can go for the battery selection. Select different battery configurations by changing the series and parallel options. There is also an option to add a custom battery, which lets you add the values of your battery configuration.img-3
  5. Next, select the “Power Mode” of your choice.
    To select the Power mode, click on the different power modes listed and see the description of each mode.
    Click the insert button to add the power mode and view the selected mode in the power profile table.
    There are different options in the power profile table which can be edited. For more information on the power profile table, check help>documentation>Power Profile table.
  6. Select the Clock mode.
    After selecting the power mode you can select and configure the available clock modes and the clock frequency. img-5
  7. Configure the peripherals.
    Peripherals play an important role in by influencing the power consumption. img-6
  8. Finally, generate your own HTML report!
    You can manage the states and profiles, view the consumption and discharge graphs and finally generate the HTML report document which contains all the necessary information you need. This report is displayed in web browser.img-7
