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.

The ATMXT144UD-SL is a touch controller containing pre-programmed firmware specifically designed for implementing a long multi-touch slider with up to 144 adjacent capacitive nodes. Its self-capacitance and mutual-capacitance acquisition, paired with its excellent intrinsic signal-to-noise performance, enables the detection and tracking of multi-finger thick gloves through a wide variety of overlay materials and thicknesses, even in the presence of moisture. With fast report rates up to 200Hz and first touch latency below 15ms, a consistent user touch experience can be achieved between the slider and an adjacent touch display. The controller incorporates internal self-tests and connected touch sensor diagnostics. ATMXT144UD-SL is offered in a small automotive qualified VQFN-56 package with wettable flanks.

The ATMXT2113TD-KD automotive touchscreen controller supports Microchip's patented Knob-on-Display™ (KoD™) technology for display sizes up to 17". The KoD™ technology allows HMI designers to combine the comfort of physical control knobs with the flexibility of modern multi-touch displays. The KoD™ technology offers the ability to reuse a standard touch sensor pattern to detect the position, direction of rotation and optionally the push function of a capacitive knob. Size, shape and position are configurable using parameters and without the need for any firmware modification. The ATMXT2113TD-KD embeds dedicated drift algorithms at the knob's location, ensuring a reliable and simultaneous operation of finger touch and capacitive knob across a range of environmental conditions. Microchip offers dedicated documentation, development tools and design services to support the development of the capacitive rotary knob as well as the bring-up and tuning at system level.
