Fujitsu microelectronics American Limited Company (FMA) It is close to already begin one from ATLab Limited Company, the flexible touch transducer controls personnel’s distribution South Korea. There is not simulation that produce and deal with the human body of digital data and touch liner of the electric conduction, FMA1127 controls personnel and changes the electric capacity.

This low power, deal with rapidly, the holding touch controller easy to realize is suitable for the mobile phone, PDA, remote controller, multimedia athletes and other movements apparatus. The touch transducer technology of the figure is considered to be easy, touch more, the intuition is entered and sailed. Control personnel waterproof can realize many kinds of materialing, make FMA1127 for suitable design alternative for alarmed system, portable health product and family apparatus, can replace mechanical switch and button for the other uses controller.

Is its Aizu-Wakamatsu apparatus in Japan using 0.25? Technological FMA produces FMA1127. The controller is relatively consulted and discerned touchll in the territory of the figure with the input impedance of transducer by development. The original touch transducer controller technology is aimed at and replaced the traditional button, and has already used DigiSensor of ATLab to be used in the touch-sensitive screen and close to the transducer now, this impedance that is exposed to causing on the finger measures unevenly. Compared with most small-scale keyboards in the mobile phone, DigiSensor which touches the controller of the transducer enables thinner, the light portable electric equipment products become possible.

Thin, light, the contact of the flexible figure
FMA1127 operates in 2.5 V to the wide voltage range of 5.5 V, the temperature between - 35°C and 85°C that and here. Can not require 0.15 mA currently, and the response time is only 0.2 ms. 8 kilovolts of ESD protect and offer to stretch / kilovolt which is exposed to liners and 15 systems / air altogether. Have no reason, need, touch liner, have outside clock pulse source to need. Equipped with interface of one I²C, FMA1127 adjusts the transducer sensitiveness based on operating environment automatically. Control personnel including automatic impedance to regulate (AIC) ,Which one support various sensitiveness for the specific straits independently, and is used for changing and regulating the interval and other parameters. AIC can be suspended and resumed using microcontroller.

The neighbouring pattern that FMA1127 includes ATLab too interferes with inhibiting (the function of filtering and dispelling the neighbouring key or pattern and interfering with) . Those FMA1127 is exposed to the controller of the transducer and offer two to be exposed to strength output and touch upon / leave the output. Two kinds of interruptseneral purposes and contacting detectionre that can be offered. The decision of touching the intensity is 8 Location (256 steps) .

Several common DIOs is amalgamated in controlling personnel too, depends on parcel type. These can take shape and programme and meet the concrete user’s needs, offer other flexibility and value.

” It represents a prominent break-through that FMA1127 inputs the device on people, use all digital processing for, enter and navigationt make light and light mobile device can one at competitive price, order very, ” The senior products sales manager in FMA, often the dean says. ” This touch transducer controller environmental protection, offer for the fact that efficient motive force is and might easy an existing microcontrollers and, family apparatus and other systems. ”

” We continue, see firm to concentrate on touch-sensitive screen technology and all main manufacturer that expect release touch-sensitive screen phone 2009 in mobile phone market. In addition, we expect it in order to see that touch tighter integration rejected with the software and hardware in 2009, will urge bigger touch-sensitive screen to adopt and carry out the transition to holding technology fast with once from resistive technology, ” Amy Leong says, executive in Gartner Dataquest’s research.

FMA1127 can be offered now in supporting up to 12 transducers input channels and many kinds of bags of 12 DIOs. -, 24 - and 30 - safety pin SSOP edition 2, DIOs 3 and 6 years old offers, and transducer 6, the input 9 and 12 years old these 20, part.

QFN wraps up and it is available too. 24 safety pin QFNs contact the controller of the transducer and offer 3 DIOs and 6 transducers to input; 32 safety pin QFNs contact the controller of the transducer and offer 8 DIOs and 9 transducers to input; And QFN of 40 pins offers 12 transducers input terminuses and 12 DIOs. Fixing the price begins 1.40 every one of quantity of 10, 000 with U.S. dollar.
