Description
The mXT2912TD-AxUW 1.0 uses a unique charge-transfer acquisition engine to implement Microchip’s patented capacitive sensing method. Coupled with a state-of-the-art CPU, the entire touchscreen sensing solution can measure, classify and track a number of individual finger touches with a high degree of accuracy in the shortest response time. The mXT2912TD-AxUW 1.0 allows for both mutual and self capacitance measurements, with the self capacitance measurements being used to augment the mutual capacitance measurements to produce reliable touch information.

Automotive Applications
• ASIL-B related FMEDA processes applied
• AEC-Q100 Qualified
• Developed following Automotive SPICE® Level 3
   certified processes
• CISPR 25 compliant (for both mutual and self
   capacitance measurements)

maXTouch® Adaptive Sensing Touchscreen
Technology
• Microchip has patents related to the Ultrawide Touch
   technology. The touch sensor, which will be developed
   by the customer, its partners, and/or Microchip for
   Ultrawide touch programs, can only be part of a touch
   solution that incorporates a Microchip touchscreen
   controller to implement the relevant functionality.
• Single ultrawide touchscreen up to 20 X lines by
   142 Y lines, made up of 40 X by 71 Y in a multiplexed
   arrangement (subject to configuration)
• Touchscreen size 34 inches (7:1 aspect ratio),
   assuming a sensor electrode pitch of 6 mm. Other
   sizes are possible with different electrode pitches and
   appropriate sensor material
• Multiple touch support with up to 16 concurrent
   touches tracked in real time

Keys
• Up to 32 nodes can be allocated as mutual
   capacitance sensor keys in addition to the
   touchscreen, defined as 2 key arrays (subject to
   availability of X and Y lines and other configurations)
• Adjacent Key Suppression (AKS) technology is
   supported for false key touch prevention

Touch Sensor Technology
• Discrete/out-cell support including glass and PET 
   film-based sensors
• On-cell/touch-on display support including TFT, LCD
   (ITPS, IPS) and OLED
• Synchronization with display refresh timing capability
• Support for standard (for example, Diamond) and
   proprietary sensor patterns (review of designs by
   Microchip or a Microchip-qualified touch sensor
   module partner is recommended)
