Procurement Notes

Verify the specific suffix AA48T against official Infineon documentation to confirm package type and temperature grade. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check current production status and lead times directly with authorized distributors as availability may vary.

Selection Notes

Select this model for applications requiring capacitive slider control rather than full touchscreen matrix handling. Ensure the design accommodates the TQFP-64 footprint and thermal requirements for the -40°C to +85°C industrial temperature range. Verify interface compatibility with the host microcontroller for I2C or SPI protocols.
