ATMXT112S-MAUR

Overview

The ATMXT112S-MAUR is a touchscreen controller from Microchip Technology's maXTouch family, designed for capacitive touch applications. It supports up to 112 reconfigurable touch channels, enabling integration with displays of varying sizes and aspect ratios. The device operates within an industrial temperature range of -40°C to +85°C and utilizes I2C or SPI interfaces for communication. Packaged in a 56-XQFN (6x6 mm) format, it is suitable for surface-mount assembly. This component serves as a dedicated solution for managing multi-touch inputs in embedded systems requiring reliable sensor processing.

Feature Summary

• Supports up to 112 reconfigurable touch channels for flexible display integration
• Operates reliably across an extended industrial temperature range
• Provides dual interface options including I2C and SPI connectivity

Applications

• Industrial control panels requiring robust touch input
• Home appliance user interfaces with medium-sized displays
• Embedded medical devices needing reliable capacitive sensing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and environmental specifications. Confirm that the selected variant matches the intended operating temperature range and interface requirements for your design. Cross-reference the part number with official Microchip documentation to avoid discrepancies in package type or firmware configuration before finalizing procurement.

Selection Notes

Select this controller when designing systems requiring up to 112 touch nodes with flexible channel mapping. Ensure the host processor supports the required I2C or SPI protocols for data exchange. Verify that the PCB layout accommodates the 56-XQFN package dimensions and thermal requirements. Consider the operating temperature range if the application involves extreme environmental conditions outside standard commercial limits.

Part Context

This component belongs to the maXTouch series, which provides integrated solutions for capacitive touch sensing. The ATMXT112S-MAUR variant specifically targets applications needing moderate channel counts with high reliability. It complements other members of the family by offering a balance between performance and pin count, suitable for mid-range display sizes in consumer and industrial electronics.

Replacement Considerations

Check for direct replacements within the ATMXT112 series with different suffixes for package or tape-and-reel variations. Evaluate newer maXTouch models if higher channel counts or updated safety features are required. Ensure any substitute maintains compatibility with existing firmware and hardware interfaces.
