Overview
The ATMXT288UD-AMBRI2CVA1 is a maXTouch 288-node touchscreen controller designed for automotive applications. It utilizes a charge-transfer acquisition engine to implement capacitive sensing, supporting both mutual and self-capacitance measurements for accurate multi-touch tracking. The device operates within an extended temperature range of -40°C to +105°C (Grade 2) and features an I2C interface supporting Standard, Fast, and Fast-mode Plus speeds. It is housed in a 56-pin VQFN package measuring 7 × 7 × 0.9 mm.
Feature Summary
- AEC-Q100 qualified and developed following Automotive SPICE Level 3 certified processes.
- Supports up to 10 concurrent touches with a typical report rate of ≥70 Hz.
- Integrated moisture compensation handles condensation or water drops up to 22 mm diameter.
- Includes noise suppression technology compliant with CISPR 25 standards.
Applications
- Automotive infotainment systems requiring robust touch input.
- On-cell or touch-on display integration for TFT, LCD, and OLED panels.
- Front panel interfaces using glass or PET film sensors.
Procurement Notes
Verify the ordering suffix 'R' confirms tape and reel packaging rather than standard trays. Confirm the 'AMB' designation matches the required Grade 2 operating temperature range of -40°C to +105°C. Ensure the I2C variant aligns with the system communication requirements instead of the SPI option.
Selection Notes
Select this component when automotive qualification (AEC-Q100) and extended temperature operation are mandatory. The I2C interface is suitable for systems prioritizing pin count efficiency over the higher throughput of SPI. Consider the 288-node capacity for displays up to approximately 6.34 inches depending on electrode pitch.
Part Context
This part belongs to the mXT288UD-AMT/mXT288UD-AMB family. The 'AMB' suffix specifically denotes the Grade 2 temperature rating (-40°C to +105°C), distinguishing it from the Grade 3 'AMT' variant which covers -40°C to +85°C. The 'R' indicates tape and reel packaging.
Replacement Considerations
The ATMXT288UD-AMTI2CVAO serves as a functional alternative if the lower Grade 3 temperature range (-40°C to +85°C) is sufficient for the application environment.
