Microchip Technology ATMXT1665TDAT maXTouch Evaluation Board

Microchip Technology ATMXT1665TDAT maXTouch Evaluation Board is a demonstration and development platform for the ATMXT1665TD-A Automotive Touchscreen Controller IC. The ATMXT1665TDAT is offered with either I2C (ATMXT1665TDAT-I2C-PCB) or SPI (ATMXT1665TDAT-SPI-PCB) communications interface.

The ATMXT1665TD-A Automotive Touchscreen Controller is aimed at display sizes up to 15"; used in center stacks, navigation systems, or rear-seat entertainment systems. The ATMXT1665TD-A 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.
