Atmel Expands Family of maXTouch S Controllers with Enhanced Nodes and Capabilities

New Touch Controllers Enable Flawless User Experience, Even for Users with Gloves On, With Passive Stylus Support for Touchscreens in Smartphones, Superphones, eReaders and Tablets

LAS VEGAS, Jan. 7, 2013 — (PRNewswire) — 2013 International CES -- Atmel® Corporation (NASDAQ: ATML), a leader in microcontroller and touch technology solutions, today announced the Atmel mXT540S, expanding its maXTouch S family of touch controllers further supporting the trend of designing larger screens into hand-held devices of various types.


Featuring 540 nodes, the new Atmel maXTouch mXT540S provides high-performance capacitive sensing for touchscreens up to 7 inches.

The new mXT540S controller delivers all the features and high-performance characteristics of the current maXTouch S family that designers have come to enjoy and grown to expect in the maXTouch S family, including thinner sensors, superior noise immunity and support for ultra-thin passive stylus. Consumers benefit from these features with a more intuitive, robust human interface for their smart, connected devices on larger touchscreens.
