Azoteq, a manufacturer in capacitive proximity and touch solutions, announced the release to market of eight ready to use trackpad modules. The trackpad modules come in a range of shapes and sizes to enable rapid integration into existing or new products. The round and elliptical trackpads are aimed at Bluetooth headset applications. Swipe and tap gestures are used for volume up/down, forward, rewind and play/pause. The square and rectangular trackpads are aimed at remote control, home automation and PC applications.

The trackpad family offers the best in class performance with scan rates from 100Hz to 220Hz and a resolution of 1792 x 1792. The modules are optimized for battery applications with operation from 1.65v to 3.6V and a standby current of 40uA. The hibernation mode on the I2C module consumes less than 1uA.
The I/O interface modules require no software and can interface directly to popular Bluetooth audio devices. These modules have 2 straps to set active high or active low outputs and select the thickness of the overlay. The I2C interface modules enable full control by the host to configure resolution, orientation and power modes. The module can track X/Y coordinates for up to 5 fingers. In I2C mode, additional two finger gestures such as pinch & zoom and two finger scroll and pan are available.
“Round and elliptical trackpads are very challenging to design and by offering a fully tested high performance module, Azoteq enables small, medium and large customers to add a trackpad with minimal design effort”, said Jean Viljoen, VP of Marketing.
