The ATMXT2952TD touchscreen controller family brings Microchip’s unmatched Adaptive Sensing technology to display sizes up to 21" used in Industrial designs. The family comprises of the following members:
1. ATMXT2952TD-C2U001/ C2UR001: First member in TD generation of 2952TD family
2. ATMXT2952TD-C2U002/ C2UR002: Compatible latest successor of the above
3. ATMXT2952TD-C2UEN1/ C2UREN1: Security Support
4. ATMXT2952TD-C2UKD1/ C2URKD1: Knob on Display Technology support with BNL Knob
5. ATMXT2952TD-C2UMK1/ C2URMK1: Knob on Display Technology support with Panasonic Knob
The TD generation enables intelligent switching between mutual capacitance and self-capacitance sensing to provide users a seamless transition between a finger touch and thick glove touch in the presence of moisture. Communication and configuration encryption as well authenticated firmware update enables users to protect confidential data such as PIN in payment systems. Proprietary differential touch sensing delivers unparalleled noise immunity ensuring superior touch performance even in harsh environments, and with a thick cover lens. Microchip’s new signal shaping technology is lowering emissions significantly and ensures that large touchscreen solutions based on the ATMXT2952TD meet customer requirements for electromagnetic interference. The controller also incorporates a comprehensive suite of self and sensor diagnostic functions, which constantly monitor the integrity of the touch sub-system.
