MTCH6301T-I/PT

Overview

The MTCH6301T-I/PT is a projected capacitive touch controller in a 44-lead TQFP package. It supports up to 13 RX and 18 TX channels, enabling multi-touch (up to ten touches) and gesture detection. The device operates on a 2.4V to 3.6V supply with an I²C interface up to 400 kbps. Key electrical parameters include a typical sleep current of 200 µA and a single-touch report rate exceeding 100 reports per second. It features built-in noise filtering, configurable sleep modes, and integrated power-on reset.

Feature Summary

• Supports up to 13 RX and 18 TX channels for flexible sensor layouts
• Enables multi-touch (up to ten points) and gesture detection (swipe, double-tap)
• I²C communication interface with a fixed 7-bit base address of 0x25
• Operates within -40°C to +105°C temperature range

Applications

• Human-machine interfaces with configurable buttons or scrolling functions
• Home automation control panels
• Security control keypads
• Automotive center stack controls
• Gaming devices and remote control touch pads

Procurement Notes

Verify the suffix 'PT' corresponds to the 44-Lead TQFP package type as specified in the datasheet. Confirm the '-I' grade indicates the industrial temperature range (-40ºC to +105ºC). Ensure the specific revision of the datasheet DS40001663B matches the silicon version required for your design integration.

Selection Notes

Select this component when designing systems requiring up to 13 RX and 18 TX channels. It is suitable for applications needing gesture recognition and multi-touch capabilities via I²C. Consider the 44-lead TQFP package constraints and the requirement for external decoupling capacitors on VDD and VCAP pins for stable operation.

Part Context

The MTCH6301 is part of Microchip's projected capacitive touch controller family. It utilizes a combination of self and mutual capacitive scanning. The device is designed for easy integration into designs using PCB, film, glass, or flexible printed circuit sensors with cover layers up to 5 mm thick.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip for alternative components if pin compatibility or feature sets differ.
