Ny generation af touch-controllere

Cypress forbedrer ydelsen og tilbyder ny features deres TrueTouch controllere (in english).

Cypress Semiconductor has introduced new, fully-integrated TrueTouch touchscreen controllers, the TMA300 family, based on the PSoC programmable system-on-chip architecture.

The new controllers offer according to Cypress best in class performance and unique features that are helping to accelerate the development of next-generation differentiated touchscreen-based user interfaces for applications in mobile handsets, portable media players, netbooks, notebooks, printers, digital still cameras, GPS systems and more.

The TMA300 family represents the next generation of multi-touch all-point technology that Cypress pioneered in 2008. The integrated analog sensing engine offers the industry’s fastest and most accurate touchscreen user experience, claims Cypress. 

This responsiveness allows tracking of multiple fingers simultaneously with precise x-y locations and without user delays or problems with erroneous 'ghost' responses. The family supports traditional gestures such as tap, double-tap, pan, pinch, scroll, and rotate, and also provides developers a unique platform to create custom gestures without being constrained to two-finger touch.

Cypress offers the TMA300 family in a tiny chip-scale package (CSP) as well as in a thin 0.6mm QFN package.  These package options give end customers a range of options for mounting the controllers on flex modules and/or directly on a printed circuit board with minimal area impact.  The new devices also support input voltages from 1.7V to 3.6V, enabling very low power consumption for battery operated devices.

Cypress has shipped millions of TrueTouch touchscreen controllers to date. The company was the first to introduce multi-touch all-point functionality and this proven technology has been in mass production since 2008. 

The TMA300 family will support a range of new features including low-cost 3mm passive stylus input, proximity detection that enables ear/face/palm rejection, water proofing and a “hover” feature that meets the touch requirements for operating systems such as Symbian, Android, Windows Mobile and Windows7. In addition, the new devices offer Cypress’s legendary noise immunity with patented capacitive sensing technology that enables flawless operation in noisy RF and LCD environments.
