Cypress Semiconductor unveiled the TMA300 family of TrueTouch touchscreen controllers. The TMA300 is based on the PSoC programmable system-on-chip architecture. The TMA300 controllers are ideal for the development of next-generation differentiated touchscreen-based user interfaces for applications in mobile handsets, portable media players, netbooks, notebooks, printers, digital still cameras, and GPS systems. The new multi-touch all-point TrueTouch family includes the CY8CTMA300E device with 32 Kbytes of Flash and the CY8CTMA301E device with 16 Kbytes of Flash. Both products are offered in 36- and 48-pin QFN packages, and the CY8CTMA300E is also offered in a tiny 49-pin chip-scale package.
The TMA300 family features an integrated analog sensing engine that results in a fast and accurate touchscreen. The responsiveness enables tracking of multiple fingers simultaneously with precise x-y locations and without user delays or problems with erroneous ghost responses. The TMA300 supports traditional gestures such as tap, double-tap, pan, pinch, scroll, and rotate. The controllers also helps developers 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. The package options give end developers a range of options for mounting the controllers on flex modules and/or directly on a printed circuit board with minimal area impact. The devices also support input voltages from 1.7V to 3.6V, enabling very low power consumption for battery operated devices.
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 of operating systems such as Symbian, Android, Windows Mobile, and Windows7. In addition, the new devices offer Cypress’s noise immunity with patented capacitive sensing technology that enables flawless operation in noisy RF and LCD environments.
