Zytronic: P-cap touch controller hardware debuts

To support its portfolio of ultra-large-format projected capacitive (p-cap) touch-sensing products, Zytronic recently launched the ZXY110.

The ZXY110 is a high-performance touch controller, described as the next generation of the company’s existing ZXY100.

Suitable for use with Windows 7, Windows 8 and Linux operating systems, the controller runs on a 32-bit ARM Cortex M4 processor capable of speeds of 168MHz, enabling Zytronic’s self-capacitive p-cap (PCT) to deliver responsiveness and precision. Updating of touch event co-ordinates is carried out by the ZXY110 in less than 5 milliseconds.

The processor is accompanied by two custom ASIC devices, which help minimise controller 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 19in diagonals, while the 64-input version is suitable for PCT sensors with diagonals of between 19in and 46in. Connection with the PC is via a USB 2.0 interface.

The touch controller may also be used with Zytronic’s freely downloadable ZyConfig software tool, which enables touchscreen integrators to access and tune the controller’s firmware settings, should they wish.
