The new MXT2912TD-UW Automotive touchscreen controller is aimed at large very wide aspect ratio displays up to 40”, used in modern car HMI systems. The trend for multiple touchscreens as well as the combination of the Central Information Display with either the cluster or the co-drive display continues. Displays and touchscreens are getting larger and significantly wider. The MXT2912TD-UW reduces the need for multiple touch controllers within a vehicle’s human machine interface (HMI) display. This single chip touch controller provides the highest report rate for wide displays and is independent of the display resolution, helping achieve the same user experience that has become accustomed with the smart phone. Also supported by the exceptional maXTouch family’s intrinsic signal-to-noise ratio (SNR), the MXT2912TD-UW enables detection and tracking of multi-finger thick gloves through a wide variety of overlays. It also supports the operation when fingers or surfaces are wet or moist, whilst preventing the water from being detected as a false touch event. This technology also enables adaptive touch utilizing self-capacitance and mutual-capacitance measurements so all touches are recognized and false touch detections are avoided. Microchip’s new signal shaping technology lowers emissions significantly and ensures that large touchscreen solutions based on the MXT2912TD-UW meet the CISPR-25 Level 5 requirements for electromagnetic interference in Automobiles. The controller also incorporates enhanced self and sensor diagnostic functions, which constantly monitor the integrity of the touch system. The MXT2912TD-UW device brings these smart diagnostic features in support of the Automotive Safety Integrity Level as specified in ISO26262. Please contact your local Microchip sales office for pricing information and to place an order.
