Atmel release with integrated LED driver 6 channel touch controller AT42QT1060

AtmEL (C) Corporation recently announced the launch of AT42QT1060, which is a combination of 6 channel touch sensing touch control chip. The chip is capable of driving up to 7 low current light emitting diodes (LED) by pulse width modulation output function. The operating voltage of the device is 5.5VDC-1.8VDC, in standby mode, the power consumption is less than 1uA, so that the battery life longer. In addition, the device uses a small size 4mm x 4mm MLF28 package, making it very suitable for mobile phones and other handheld devices. Complete in Atmel, based on Quantum Research Group power

AT42QT1060 series is the newest member of the capacitive touch controller series. These controller families include QTouch and QMatrix (TM) controllers for single and multi touch buttons, touch scroll bars, and touch wheels.

AT42QT1060 designed for portable electronic products. Built in capacitive protection channel function helps prevent accidental touch, for example, in wet conditions. This feature can also be used to prevent errors. This can happen when the MP3 player is placed in a pocket or when the phone is facing the ear. Highly integrated AT42QT1060 reduces the number of components, which reduces the complexity and cost of the design, and can accelerate product development.

The patented QTouch (TM) charge transfer sensing method based on Quantum for the sensor chip. This outstanding technique using spread spectrum modulation to achieve high immunity to electrical noise, and patented technology Adjacent KeySuppression (TM) (AKS (TM)) is to ensure that only a finger touch when setting button is activated will be good. This protection channel features the use of AKS (TM) to avoid misuse of nearby keys. The device has a long term reliability, since it can be automatically re calibrated at startup to deal with the formation of moisture or other contaminants on the touch screen. The host can also set the sensitivity of a single key.

When the user starts the corresponding input, the host wake up function allows the host to sleep and wake up, providing a power-saving function. Use the spare IC pin can also achieve more GPIO expansion function.

AT42QT1060 operates through any insulation board, including 3mm thickness of glass or plastic. Electrodes can be made of copper, silver, carbon, indium tin oxide or Orgacon conductive ink, and the area must be 6 x 6mm or greater. Because of the size or shape of the electrode can be used, which can create a user interface for product designers to bring greater flexibility.

Listing and pricing

AT42QT1060 samples are now available in space saving 4mm x 4mm packaging launch. The price per 100000 pieces per year is $0.89. Demo board has also been launched.
