ATMXT2912TD-ATUWVAO

Overview

The ATMXT2912TD-ATUWVAO is a maXTouch touchscreen controller utilizing a charge-transfer acquisition engine for capacitive sensing. It supports up to 2911 nodes, enabling single ultrawide touchscreens with dimensions up to 34 inches (7:1 aspect ratio). The device tracks up to 16 concurrent touches and includes on-chip gesture reporting. It operates within an industrial temperature range of -40°C to +85°C and features I2C and SPI interfaces. The component is housed in a 176-lead LQFP package.

Feature Summary

Supports single ultrawide touchscreens up to 20 X lines by 142 Y lines
Tracks up to 16 concurrent touches with initial latency under 20 ms
Includes moisture compensation for water drops up to 22 mm diameter
Features AEC-Q100 qualification and Automotive SPICE Level 3 development processes

Applications

Automotive infotainment systems requiring ASIL-B compliance
Large display panels supporting glass or PET film sensors
On-cell and touch-on-display implementations including TFT and OLED

Procurement Notes

Verify the ordering suffix 'VAO' indicates standard tray packaging as specified in the product identification system. Confirm that the 'AT' suffix corresponds to the Grade 3 operating temperature range of -40°C to +85°C. Ensure firmware revision 1.0.AA compatibility requirements are met for the target application design.

Selection Notes

Select this controller for applications requiring high node counts and wide aspect ratios. Verify sensor stack-up approval by Microchip or qualified partners for curved profiles or non-rectangular designs. Consider the 176-lead LQFP footprint constraints and ensure adequate thermal management for the specified operating temperature range.

Part Context

This part belongs to the mXT2912TD-AxUW family, which implements Microchip's patented capacitive sensing method. The device integrates mutual and self-capacitance measurements to provide robust touch detection. It is designed for automotive environments, adhering to CISPR 25 standards and utilizing Adaptive Sensing Touchscreen Technology.

Replacement Considerations

The ATMXT2912TD-ATRUWVAO serves as a functional substitute with identical electrical specifications but utilizes tape and reel packaging instead of trays.
