alternative touch controller is ATMXT1066T2.
A 1386-node multi-chip solution (4-chips) which is part of the
Microchip maXTouch product platform. The high performance
architecture enables unlimited touch up to 16 touches, fast response
time at over 150Hz, and smart processing of a capacitive touch image to
accurately regenerate and report user interaction with the touchscreen. The device features
multi-touch performance, enabling touches to be identified and
individually tracked and allowing a range of built-in gestures to be
reported to the host processor. The mXT1386E is capable of supporting up to 15.6" touchscreens and supports host interfaces like
I2C and USB.
Support: off the shelf maXTouch standard modules are available
to help shorten development time and reduce risk. Microchip also has a strong
selection of factory trained global touch sensor module partners to help
support custom touch sensor and/or touchscreen display designs.
