Touch controller is capable of running at speeds of 168MHz

The controller's processor is accompanied by two sophisticated custom ASIC devices which help minimise footprint, while maximising touch detection performance, even through cover glass thicknesses exceeding 10mm.

The ZXY110 is offered in two different versions; the 32-input version covers PCT p-cap touch sensors with up to approximately 19" diagonals, while the 64-input version is suitable for PCT sensors with diagonals of between 19 and 46". Connection with the PC is via a USB 2.0 interface.

Updating of touch event coordinates is carried out by the ZXY110 in less than 5ms, resulting in a satisfying user experience. This product’s key attribute is proprietary architecture and firmware providing resilience to EMI. This ability to combat EMI comes from the touch controller’s ‘smart' frequency-scanning function, where the operating frequency moves dynamically between 1.3 and 2.5MHz in order to avoid detected environmental noise that would otherwise prevent the detection of touch events.

Suitable for use with Windows 7,Windows 8 and Linux OSs, this item of hardware is a plug and play HID. The touch controller may also be utilised in conjunction with Zytronic’s freely downloadable ZyConfigsoftware tool, which enables touchscreen integrators to access and tune the controller’s firmware settings.

To ease implementation, the ZXY110 shares the same mounting arrangement as the ZXY100 touch controller. As a result, the device can be retrofitted in order to enable performance improvements to existing PCT based touch system designs. Furthermore, there is potential for OEMs requiring high volumes to enter into ZXY110 chipset agreements with Zytronic, in order to embed the controller onto a motherboard in space critical applications.
