Azoteq IQS525 projected capacitive touch and proximity
trackpad/touchscreen controller features high sensitivity, excellent
signal to noise ratio, and automatic tuning of electrodes. Low power
proximity detection allows for extremely low power operation. IQS525
delivers 25 channels with a minimum report rate of 220Hz and a
resolution of 1280 x 768. It is ideal for compact capacitive keyboards,
remote control trackpads, and portable devices. IQS525 is offered in a
28 pin QFN package.
Azoteq Touch Sensor Development Tools deliver new trackpad technology that enable cost sensitive applications to add a trackpad, such as remote controls and wireless keyboards. Azoteq Touch Sensor Development Tools provide a plug and play trackpad and combine two familiar interfaces, trackpad and tactile keys.
The purpose of IQS525-TP43-HID-S is to illustrate the capabilities of the
IQS525-TP43 module and to serve as a design example of how such a trackpad
module can be used in conjuction with a microcontroller.
