MTCH6303T-I/PT

Overview

The MTCH6303T-I/PT is a projected capacitive touch controller in a 64-pin TQFP package. It supports up to 27 RX and 19 TX channels for multi-touch surfaces, typically handling ten touches at 100 Hz. The device integrates gesture recognition for swipes, scrolling, pinching, and zooming. Communication is selectable via USB or I2C using the COMM_SEL pin. It operates with a 3V supply and includes an integrated boost driver interface for high-voltage line driving.

Feature Summary

• Multi-touch support for up to ten fingers with predictive tracking
• Integrated single and multi-finger gesture recognition suite
• Selectable USB or I2C communication interfaces
• Advanced noise avoidance techniques for reliable operation

Applications

• Industrial control panels and security systems
• Home and office automation devices
• Medical equipment input interfaces
• Consumer audio and exercise equipment

Procurement Notes

Verify the specific suffix 'I/PT' corresponds to the industrial temperature range and TQFP-64 package. Confirm that the required MTCH652 high-voltage driver is included in the system design, as it is necessary for full functionality. Check for any product change notifications regarding firmware updates or packaging modifications.

Selection Notes

Select this component when a turnkey solution with built-in gestures is required. Ensure the host system can support either USB HID or I2C protocols based on the COMM_SEL pin configuration. Verify that the sensor layout fits within the 27x19 channel constraint for the target screen size.

Part Context

This part belongs to the MTCH6303 family of projected capacitive touch controllers. It is designed to work in conjunction with the MTCH652 high-voltage line driver to achieve superior signal-to-noise ratios in noisy environments. The device is pre-programmed with a Library Loader bootloader for firmware customization.

Replacement Considerations

The MTCH6301T-I/ML is a related controller in the same family but offers different memory specifications and channel configurations. Verify compatibility if substituting, as pinouts and feature sets may differ.
