Azoteq Announces the IQS5XX-B000 family of Trackpad and Touchscreen controllers 

October 7, 2015 - Azoteq, the world leader in proximity and touch solutions, announced the release to market of the IQS5XX-B000 family of Trackpad and Touchscreen controllers. The IQS5XX-B000 adds many new features to the very successful IQS5XX-A000 family. IQS5XX-A000 devices can be upgraded to the IQS5XX-B000 via the boot loader.


The IQS5XX-B000 family offers the best in class performance with scan rates up to 220Hz and a resolution up to 3584 x 2304. The IQS5XX-B000 family is optimized for battery applications with operation from 1.65v to 3.6V and 40uA operating while scanning in low power mode and less that 1uA in hibernation mode.

Designers can lay the row and column electrodes out in any order and in software define the electrodes to be in sequential order. The X and Y resolution can be configured independently and the orientation set to meet the application requirements. The IQS5XX-B000 devices can track coordinates for up to 5 fingers.  The devices support 15 one and two finger gestures such as tap, scroll, pinch & zoom and two-finger scroll. All configuration parameters can be stored in NV memory on the device so that the device is fully functional after power up without a long setup procedure.

“The IQS5XX-B000 family was designed to offer maximum flexibility and yet make the PCB design and software as easy as possible for the designer,” said Kobus Marneweck, VP of Marketing.
