Aito controller enables touch keys on any surface

Aito's new ATB250 AitoTouch controller provides a highly configurable user interface for up to eleven touch buttons on any surface, replacing traditional mechanical switches.

The controller overcomes the problems of capacitive and other touch technologies that either require significant button travel or will not operate with gloved hands or through metal panel overlays.

The ATB250 provides a combination of input and output channels to support up to eleven piezo touch buttons, each with drivers for LED indicators to provide visual feedback, along with a single buzzer output for audible feedback.

The piezo sensing parameters for each key can be individually configured for sensitivity, detection area and to cope with different overlay stiffness or mechanical integration conditions.

The LED and buzzer feedback patterns can be customised for each key. For easy integration into existing hardware, the device offers SPI, I2C and DEO (Digital Encoded Output) mode interfaces for communication with the host processor.
