Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with required sensor stack-ups and firmware versions before procurement.

Selection Notes

Select this component for applications requiring high node counts and robust environmental performance. Confirm that the system design accommodates the 176-lead LQFP package dimensions and power supply requirements.

Part Context

This part belongs to the mXT2912TD-A family, designed specifically for automotive touchscreen controllers. It shares core architecture with the Grade 3 (-40°C to +85°C) variant but offers extended temperature capability suitable for harsh automotive environments.

Replacement Considerations

The ATMXT2912TD-ATVAO serves as a functional alternative with identical electrical characteristics but a reduced operating temperature range of -40°C to +85°C.
