Touch Screen Controllers Procurement Notes

Verify the specific suffix AS46T against official Infineon documentation to confirm package type and moisture sensitivity level. Confirm that the required factory packaging quantity aligns with project needs, as standard reels may contain 1500 units. Ensure compliance with RoHS directives and check for any specific humidity sensitivity handling requirements during storage and assembly.

Touch Screen Controllers Selection Notes

Select this controller for applications requiring high-resolution capacitive touch sensing in automotive environments. The integrated Arm Cortex CPU allows for complex gesture recognition and noise immunity algorithms. Ensure the host system supports the required I2C or SPI protocols and can provide the necessary 1.71 V to 5.5 V power supply range for stable operation.

Touch Screen Controllers Part Context

This component belongs to the CYAT82687 series, which represents Infineon's TrueTouch Gen6XL line. These controllers are specifically engineered for automotive-grade reliability and performance.
