ATMXT144UD-A

The ATMXT144UD-A is the smallest Automotive qualified touchscreen controller in a VQFN-56 package with wettable flanks, aimed at smart surfaces and multi-function displays up to 4.3”.

Excellent intrinsic SNR of this latest maXTouch family enables detection and tracking of multi-finger thick gloves through a wide variety of overlay materials and thicknesses, even in the presence of moisture. This SNR combined with a high acquisition speed provides a fast, accurate and reliable a touch position.

The ATMXT144UD-A incorporates a new low power mode for wake-up on touch, this enable the system to go into a wait-for-touch mode while consuming less than 50uA and to wake-up by a touch event anywhere on the touch surface.

This technology also enables adaptive touch utilizing self-capacitance and mutual-capacitance measurements so all touches are recognized and false touch detections are avoided.

The controllers also incorporate a new self and sensor diagnostic function, which constantly monitors the integrity of the touch system. The new ATMXT144UD-A device brings these smart diagnostic features in support of the Automotive Safety Integrity Level as specified in ISO26262.
