Zytronix launches ARM Cortex A4 touch controller

Zytronic has added an ARM Cortex A4-based touch controller called the ZXY110.

It runs at 168MHz enabling Zytronic’s self-capacitive p-cap (PCT) sensors to gain in responsiveness and precision.

The processor is accompanied by two ASICs which help minimise controller footprint, while maximising touch detection performance, even through cover glass more than 10mm thick.

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

Updating of touch event co-ordinates is carried out by the ZXY110 in less than 5msec.

The device features proprietary new architecture and firmware providing resilience to electro-magnetic interference (EMI). This comes from its ‘smart’ frequency-scanning function, where the operating frequency moves dynamically between 1.3MHz and 2.5MHz  to avoid observed environmental ‘noise’ that would otherwise prevent the detection of touch events.

Suitable for use with Windows 7, Windows 8 and Linux operating systems, the controller is a plug-and-play human interface device (HID) that can be used in conjunction with Zytronic’s downloadable ZyConfigTM software tool, which enables touch screen integrators to access and tune the controller’s firmware settings.

To ease implementation, the ZXY110 shares the same mounting arrangement as the company’s ZXY100 touch controller so it can be retrofitted to existing PCT-based touch system designs.
