Freescale’s Sensor Hub Integration

We’ve seen the move from APs managing sensors to MCUs acting as sensor hubs to integration of sensors with MCUs, as with ST. Well, Freescale has now jumped in as well, integrating an accelerometer with a 32-bit Coldfire V1 MCU into what they’re calling their Xtrinsic Intelligent Motion platform.

Given the number of IMUs out there integrating accelerometers, gyros, and magnetometers, I asked why they were just going with an accelerometer only. They said that, frankly, in earlier days, customers didn’t seem interested in sensor hubs. They’re coming around, and clearly they’ve made their way into phones. But now industrial and other customers are starting to take note. But they’re not so much interested in the gyros and magnetometers.

That’s not to say you can’t use them; you can add other sensors into the hub via their I2C/SPI connectivity.

One of the other challenges they see for users is the fact that most sensor hub environments are closed, limiting your choice of sensors and software. They’re trying to keep things as open as possible, allowing you to integrate whatever other sensors and software they want from any vendors they choose. Freescale will provide free software, but you’re not locked in.

You can find more information in their release.

Mission Critical Electrical Controls

Sponsored by Mouser Electronics and Littelfuse

If you are working on a mission-critical design, there is a very important list of requirements that you will need to consider for your electromechanical controls including how well they have been tested, availability of inventory, and the quality of the components. In this episode of Chalk Talk, Amelia Dalton chats with John Saathoff from Littelfuse electromechanical solutions offered by Hartland Controls, the benefits Hartland brings to the table when it comes to mission-critical designs, and how you can get started using Hartland Controls for your next design.
