Overview
The ATMXT336S-CCUR is a maXTouch touchscreen controller IC manufactured by Microchip Technology. It supports up to 336 nodes for complex touch interfaces. The device operates on a single supply voltage ranging from 1.71V to 3.63V. It features an I2C interface for communication with host processors. The component is available in a QFN package and is rated for industrial temperature operation between -40°C and +85°C.
Feature Summary
- Supports high-node-count capacitive sensing for advanced gesture recognition
- Integrates self-capacitance and mutual-capacitance channels
- Includes built-in noise cancellation and environmental adaptation algorithms
Applications
- Industrial control panels requiring robust touch input
- Medical equipment interfaces demanding reliability
- Automotive infotainment systems
Procurement Notes
Verify the specific suffix 'CCUR' against official Microchip documentation to confirm package type, temperature range, and tape-and-reel specifications. Ensure compatibility with existing firmware libraries before procurement. Check current lifecycle status as components may be subject to obsolescence notices.
Selection Notes
Select this model when a high node count exceeding standard controllers is required. Compare power consumption metrics against alternative maXTouch series devices if battery life is critical. Verify that the host system supports the required I2C clock speeds and voltage levels for reliable data transfer.
Part Context
This part belongs to the ATMXT336U family of maXTouch controllers. It shares core architecture with other variants in the series but differs in packaging and thermal ratings. The 336-node capacity distinguishes it from lower-density models like the ATMXT1664 or ATMXT640.
Replacement Considerations
Direct replacements within the maXTouch family include the ATMXT336U-MAUR. Verify pinout compatibility and firmware support before substituting. Alternative suppliers may offer pin-compatible parts, but electrical characteristics must match exactly.
