Atmel Company develops AT42QT1040, convenient, easy to realize, the low cost contacts the transducer IC, which area letting user’s interface is given to price sensitive consumers and mobile devices.

AT42QT1040 can be offered in one 3 millimetre x 3 millimetres x 0.85 millimetres VQFN 20 safety pins of bags, it make it suitable for at premium PCB space in cellular telephone and apparatuses portables other in use. Draw pieces of 31µA offer from one 1.8 Vdc of low power ways in AT42QT1040, allow person who hold feel with to minimum influence all one’s life such as battery that increase.

The latest solution of the apparatus contacts the transducer to divide from Atmel, which development holding contact button, the slide, the wheel and touch-sensitive screen controller. AT42QT1040 includes the output passways of 4 figures, enable the becoming possible about the sign perceived in touch of every straits. IC can use a piece of straits as one and close to the transducer to enable and take shape too, in have one distance discern one present place of finger make user interface become possible from apparatus to small-scale keyboard.

AT42QT1040 shifts and feels the method on the basis of QTouch electric charge of Atmel. Technology uses the frequency spectrum of expanding to modulate and reach the high immunity to the electric noise. Neighbouring key of Atmel inhibit from, technology, for key that throw closely being essential, used for, guarantee the key of plan start because of one touch of finger only. Long-term dependability obtain, because apparatus automatic to keep check-up always in power check-up upwards, even touching it is influenced that the growth that there are a moisture or other pollutant on the surface or whole system is worn out. Specific key sensitiveness can take shape and support including glass or plastics are up to many kinds of panel thickness and material several millimetres thick. Electrode might by copper, silver, carbon, indium tin oxide or any other electric conduction of materials make. Extensive and different electrode size and form are possible, give products designer’s big interface of adjustment user of flexibility.

The apparatus has two kinds of power ways: A low power way, suitable for small, battery-operated apparatus and a fast response way, offer the minimum response time for the fact that it is an essential application that the low touch hides. In order to help product development, AT42QT1040 has a debugging way in which internal data from one can be entered. Ability behavior of apparatus that control indicate, design, can cause with the method appraise and debug rapidly, design time frames in a kind of narrower products.

AT42QT1040 pricing is 0.35 dollars of the quantity of 100, 000. One assess tool, EVK1040A, can also offer, price at so as to 25 dollars.
