The ATMXT2113TD-A Automotive
touchscreen controller is aimed
at display sizes up to 15" and larger; used in center stacks, navigation systems or rear
seat entertainment systems. This
brand new family of automotive touchscreen
controller brings Microchip’s unmatched Adaptive Sensing technology to the Automotive
market. Microchip’s latest solution
offers superior signal-to-noise capability to address the requirements of thick
lens and thick glove support; supporting multiple thick gloved touches
and 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 is lowering emissions significantly and ensures
that large touchscreen solutions based on the ATMXT2113TD-A
meet the CISPR-25 Level 5 requirements for electromagnetic interference in
Automobiles.
The controllers also incorporate a new self and sensor diagnostic
function, which constantly monitors the integrity of the touch system. The new ATMXT2113TD-A device brings these smart diagnostic features in
support of the Automotive Safety Integrity Level as specified in ISO26262.
