The Azoteq IQS550-A000 150-channel capacitive proximity and touch controller enables new applications

Austin, TX (PRWEB) December 20, 2012

Azoteq, the world leader in capacitive proximity solutions, today announced the release to market of the IQS550-A000 Capacitive Trackpad and Touch Screen Controller. The IQS550-A000 is Azoteq´s latest addition to the ProxSense® family of capacitive proximity and touch controllers. The IQS550-A000 offers high-resolution touch and hover to track up to five fingers. The extended proximity detection allows the IQS550-A000 to operate in a low power mode, but to wake up instantly to detect touch when proximity is detected.

The IQS550-A000 Capacitive Trackpad Controller is the first in a family of products that will be implemented on the flexible IQS550 platform. The IQS550-A000 uses advanced analog and digital circuitry to achieve unparalleled proximity and touch performance. The high sensitivity enables the IQS550-A000 to work reliably through thick overlays, and even through membrane switch overlays. The device can operate from 1.65 to 3.6 V and achieves power consumption as low as 15 microampere while still sensing proximity. The IQS550-A000 features an I2C interface for convenient control from a host MCU.

“The IQS550 platform represents a major breakthrough in flexibility for Azoteq. Azoteq will offer the IQS550-A000 Capacitive Trackpad Controller as a first configuration, but the same platform will enable other configurations to be offered to the market shortly,” said Kobus Marneweck, Azoteq´s VP of Marketing.

The IQS550-A000 Capacitive Trackpad Controller is Azoteq´s first capacitive touch controller capable of interfacing with Trackpads and Touch screens as large as 7 inches. In the next few months, Azoteq will introduce smaller versions of the IQS550 for smaller Trackpads or applications that do not require the high resolution of the IQ550.
