The Atmel ATMXT641T-AT is an advanced touchscreen controller designed for high-accuracy touch sensing. It employs a unique charge-transfer acquisition engine and a state-of-the-art CPU to measure, classify, and track multiple finger touches with minimal response time.
Key features include support for up to 32 X (transmit) lines and 20 Y (receive) lines, allowing for a maximum of 640 nodes. The device enables multiple touch support, tracking up to 16 concurrent touches in real time. It is AEC-Q100 Qualified and developed following Automotive SPICE Level 3 certified processes, making it suitable for automotive applications.
The controller supports both mutual and self-capacitance measurements, enhancing touch reliability. It offers robust touch performance with moisture/water compensation for condensation or water drops up to 22 mm and glove support for multiple fingers up to 1.5 mm thick or single fingers up to 5 mm thick. Noise suppression technology combats ambient and power-line noise, ensuring stable operation.
The ATMXT641T-AT is compatible with various touch sensor technologies, including discrete/out-cell (glass and PET film) and on-cell/touch-on display (TFT, IPS, OLED). It works with front panel materials like glass (0.5 mm to 2.0 mm) and plastic (0.2 mm to 3.0 mm), including curved profiles.
