Leveraging Immersion’s TouchSense haptics technology, the Atmel AT42QT1085 QTouch 8-key touch sensor IC is claimed the first capacitive touch controller in the industry to provide haptics support for buttons, sliders, and wheels for 14 unique haptic effects. Haptics enables design engineers the ability to add tactile feedback to greatly enhance the user experience for applications such as mobile phones, game consoles, navigation devices, cameras, netbooks, appliances, and PCs. Haptic events may be triggered by touch detection or controlled by a host microcontroller over SPI.
The AT42QT1085 features a dual pulse key measurement/touch detection method, power-on reset and brownout detection, internal calibrated oscillator, and 12 dedicated bidirectional GPIO pins, plus up to four additional pins (replacing keys). It also offers self-calibration, noise drift compensation, and a patented adjacent key suppression technology to ensure accurate key detection. Housed in a 32-pin MLF or TQFP package, the part operates from 2.0 to 5.5 V and uses master/slave SPI interface (up to 750 kHz). ($1.50 ea/1,000 — available May.)
