Procurement Notes

Verify the specific suffix MAHR against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing firmware drivers before procurement. Check for recent product change notifications that may affect pinout or electrical characteristics. Confirm availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when a high node count is required for large display areas. Compare with lower node variants if cost reduction is prioritized over feature set. Verify that the host processor supports the required I2C clock speeds. Consider power consumption requirements relative to other MaxTouch family members.

Part Context

This part belongs to the Atmel MaxTouch MXT224 series of capacitive touch controllers. It is designed for applications requiring extensive touch zones and complex gesture support. The E-MAHR suffix typically denotes specific packaging and environmental ratings defined by the manufacturer.

Replacement Considerations

Direct substitutes include other MXT224 variants with different suffixes for package or temperature changes. Cross-reference with MXT224T or MXT224Q models if pin compatibility differs. Verify firmware compatibility when switching between similar node-count devices.
