Overview
The MTCH6301-I/PT is a projected capacitive touch controller from Microchip Technology, housed in a 44-lead TQFP package. It supports up to 13 RX and 18 TX channels for multi-touch 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 an operating temperature range of -40°C to +105°C. Touch performance exceeds 100 reports per second for single touch and 60 for dual touch, providing 12-bit coordinate resolution.
Feature Summary
- Supports up to 10 simultaneous touches with gesture detection and reporting capabilities.
- Integrates Self and Mutual Capacitive scanning for XY screens and touchpads.
- Features configurable sleep mode with integrated Power-on Reset and Brown-out Reset.
- Includes built-in noise detection and filtering algorithms.
Applications
- Human-machine interfaces with configurable buttons, keypads, or scrolling functions
- Single-finger gesture-based interfaces for swipe, scroll, or double-tap controls
- Home automation control panels
- Security control keypads
- Automotive center stack controls
Procurement Notes
Verify the specific suffix '-I/PT' corresponds to the Industrial temperature grade (-40°C to +105°C) and the 44-Lead TQFP package type as defined in the official datasheet. Confirm that the ordering information matches the exact part number required for your design specifications before procurement.
Selection Notes
Select this component when designing applications requiring robust multi-touch and gesture recognition via I²C. Ensure the host microcontroller supports the required I²C clock speed and can handle the interrupt-driven data protocol. Verify that the sensor layout configuration aligns with the available RX/TX channel mapping options provided by the controller.
Part Context
The MTCH6301 is part of Microchip's mTouch sensing solution family. It is designed to work with various sensor materials including PCB, film, glass, and flexible printed circuits. The device allows for extensive customization through a PC-based configuration utility and supports storing configuration data in nonvolatile RAM for persistent settings across power cycles.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip technical support or authorized distributors for alternative components if the MTCH6301-I/PT is unavailable.
FAQ
What is the default sensor configuration for the MTCH6301?
The MTCH6301 is preconfigured for a 12 Receiver (RX) and 9 Transmitter (TX) touch sensor setup out-of-the-box.
How does the MTCH6301 communicate touch data to the master controller?
It uses an I²C serial streaming format where the INT pin is asserted to signal the master that new touch or gesture data is ready for transmission.
Can the RX and TX pins be remapped?
Yes, all RX/TX pins are remappable via Pin Map register arrays to facilitate convenient trace routing and board layout.
