Microchip Technology introduced their MTCH101, MTCH112, MTCH810 and MTCH6301 turnkey controllers. The new devices are ideal for multitouch projected-capacitive touchscreens and touchpads, proximity detection, and haptic touch feedback. All of four of the controllers are available now for sampling. Volume production is expected next month.
The MTCH6301 turnkey projected-capacitive touch controller makes it easy for designers to add multitouch and gesture interfaces. The controller features Self and Mutual capacitive scanning for XY touchscreens and touchpads. The MTCH6301 enables features like single and dual-touch drawing, the reporting of 11 single-finger gestures and the detection of up to 10 touches. The device supports sensor designs with up to 13 x 18 channels and cover lenses up to 5 mm.
The MTCH101 and MTCH112 turnkey controllers provide an easy way to add robust proximity detection with a range of up to 8 inches. The low-cost controllers maximize battery life with power consumption as low as 5 microamps. The MTCH101/112 also provide advanced noise avoidance and cancelling technology, and can operate standalone or connected to any microcontroller via I2C.
The MTCH810 is based on Immersion’s TouchSense haptic feedback technology. The controller enables the easy addition of haptic tactile feedback to any capacitive-touch button or slider interface. It integrates a single-channel haptic driver output with an industry-standard I2C slave interface that connects to any MCU — all in a small, 8-pin package.
The MTCH6301 projected-capacitive controller is available in 44-pin QFN and TQFP packages. Prices start at $1.86 each, in 10,000-unit quantities. The MTCH101/112 proximity-detection controllers start at $0.25 each, in 10,000-unit quantities. The MTCH101 is offered in a 6-pin, SOT-23 package, while the MTCH112 is packaged in the 8-pin SOIC and DFN. The MTCH810 haptic-feedback controller is available in a 3×3 mm, 8-pin DFN package. Prices start at $0.87 each, in 10,000-unit quantities.
