MTCH6303-I/PT

Overview

The MTCH6303-I/PT is a projected capacitive touch controller in a 64-pin TQFP package. It supports up to 27 RX and 19 TX channels, enabling multi-touch tracking for ten fingers at approximately 100 Hz. The device integrates gesture recognition for taps, swipes, scrolling, pinching, and zooming. It features USB and I2C communication interfaces selectable via the COMM_SEL pin. Advanced signal processing provides noise avoidance and predictive tracking. When paired with the MTCH652 high-voltage line driver, it achieves superior signal-to-noise ratio for reliable operation in noisy environments.

Feature Summary

• Multi-touch support for up to ten simultaneous touches
• Integrated single and multi-finger gesture recognition suite
• USB and I2C communication protocols
• Advanced noise avoidance and predictive tracking technology

Applications

• Industrial control panels and home automation systems
• Medical devices and office equipment such as printers
• Consumer electronics including audio systems and exercise equipment

Procurement Notes

Verify that the design includes the required MTCH652 high-voltage boost driver, as the MTCH6303 requires it for full functionality. Confirm the COMM_SEL pin configuration matches the intended interface (I2C or USB). Ensure firmware updates are handled via the integrated bootloader if custom gestures are needed.

Selection Notes

Select this component for designs requiring cost-effective PCAP solutions with minimal host processor overhead. The 64-pin TQFP package suits applications needing up to 8-inch touch screens. Consider the MTCH652 companion chip for enhanced performance in electrically noisy industrial settings.

Part Context

The MTCH6303-I/PT is part of Microchip's turnkey touch controller family. It is designed to simplify UI integration by providing pre-programmed gesture libraries. The 'I' suffix indicates industrial temperature range, and '/PT' denotes the 64-pin TQFP packaging option.

Replacement Considerations

The MTCH6301T-I/ML is a related controller within the same product family. Verify channel count and package compatibility before substitution, as the MTCH6301 may have different resource allocations.
