Cypress introduces touchscreen controller range

The controllers offer features that help 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 and GPS systems.

The integrated analogue-sensing engine 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 provides developers with a platform to create custom gestures without being constrained to two-finger touch.

Cypress offers the TMA300 family in a chip-scale package (CSP) as well as in a 0.6mm QFN package.

These packages give 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 devices also support input voltages from 1.7 to 3.6V, enabling low power consumption for battery operated devices.

The TMA300 family will support a range of 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 devices offer noise immunity with capacitive sensing technology that enables flawless operation in noisy RF and LCD environments.

The flexibility and best-in-class performance of the Truetouch solution allow customers to develop leading-edge solutions without having to buy turnkey modules.

The Truetouch family includes the CY8CTMA300E device with 32Kb of Flash and the CY8CTMA301E device with 16Kb of Flash.

Both products are offered in 36- and 48-pin QFN packages, and the CY8CTMA300E is also offered in a 49-pin chip-scale package.
