maXTouch® 1066-node Touchscreen Controller Microchip Technology maXTouch® 1066-node Touchscreen Controller uses a unique charge-transfer acquisition engine to implement Microchip’s patented capacitive sensing method. The touchscreen sensing solution can measure, classify, and track the number of individual finger touches with a high degree of accuracy in the shortest response time. This mXT1066TD 1.0 controller allows for both mutual and self-capacitance measurements. These self-capacitance measurements used to augment the mutual capacitance measurements to produce reliable touch information. The maXTouch controller also incorporates a new self and sensor diagnostic function, that constantly monitors the integrity of the touch system.
