Procurement Notes

Verify availability status as distribution channels may indicate limited sales in specific regions. Confirm package type LQFP-176 and interface compatibility (I2C/SPI) against system requirements. Check operating temperature specifications (-40°C to +85°C) for environmental suitability before procurement.

Selection Notes

Select this component when high node count (2800) is required for large or wide displays. Ensure the design supports LQFP-176 footprint and SMD/SMT assembly processes. Validate that the host system can handle I2C or SPI communication protocols at the specified voltage levels.

Part Context

This part is part of Microchip's ATMEL maXTouch family, specialized for multi-touch applications. It integrates touch sensing and processing capabilities into a single IC, reducing board space compared to discrete solutions. The ATRUWVA1 suffix denotes specific packaging and tape/reel configuration details.

Replacement Considerations

Check Microchip documentation for direct pin-to-pin replacements within the ATMXT series. Verify node count and interface compatibility when considering alternative controllers. Ensure thermal and electrical specifications match the original design constraints.
