Atmel has confirmed that two new maXTouch touchscreen controllers were recently certified for use in next-gen automobiles. The mXT1188S is optimized for touchscreens up to 12 inches, while the mXT1664S is targeted at touchscreens up to 14 inches.
Both touchscreen controllers are optimized for single-layer shieldless sensor designs in automotive center consoles, navigation systems, radio interfaces and rear-seat entertainment systems. Meanwhile, a single-layer shieldless sensor design eliminates additional screen layers, effectively delivering improved light transparency. This results in lower power consumption, along with an overall lower system cost for the manufacturer.
The above-mentioned maXTouch controllers are AEC-Q100 compliant and designed for high reliability in harsh environments. They also offer glove support and improved moisture resistance – two key requirements for touch screen use in vehicles.
“The new automotive-qualified maXTouch controllers further strengthen Atmel’s automotive market position enabling more touchscreens in the car to hit the streets,” said Rob Valiton, Senior Vice President and General Manager, Automotive, Aerospace and Memory Business Units.
“We are also making in-car systems with capacitive touchscreens more accessible by enabling a shieldless single-layer touch sensor, which significantly reduces the total system cost. [Simply put], Atmel’s maXTouch controllers deliver superior touch performance, multi-touch, faster response times, more precise touches, robust operation and lower power consumption for an excellent user experience.”
To help accelerate design, Atmel is currently offering the EVK-MXT1664SAT-A evaluation kit, which includes an mXT1664S touch controller that interfaces with a 10.1-inch sensor (with an aspect ratio of 16:9). It should be noted that samples of the mXT1664S-A and mXT1188S-A in LQFP144 packages are available now, while devices in the PPAP packages will ship in June 2014 with volume production by July 2014.
