Decoupling Capacitors
The use of decoupling capacitors on power supply pins,
such as VDD and VSS, is required (see Figure 5-1).
Consider the following criteria when using decoupling
capacitors:
1. Value and type of capacitor:
A value of 0.1 µF (100 nF), 10-20V is recommended. The
capaci...

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at docerrors@microchip.com. We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any
page. The last character of the literature number is the version number, (e.g., DS30000000A is version A of document
DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.

1.0 SYSTEM BLOCK DIAGRAM
2.0 CONFIGURATION AND SETUP
The MTCH6301 is preconfigured for a
12 Receiver (RX)/9 Transmitter (TX) touch sensor, mapped as
shown in Section 5.1 “Typical
Application Circuit”. While the device will work out-
of-the-box using this specific sensor configuration,
most applications will require additional configuration
and sensor tuning to determine the correct set of
parameters to be used in the final application.
Microchip provides a PC-based configuration tool for
this purpose, available in the mTouch™ Sensing
Solution Design Center (www.microchip.com/mtouch).
Use of this tool requires a PICkit™ Serial Analyzer (
updated with MTCH6301 support), as well as access
to the I2C communications bus of the MTCH6301
device.
Once the development process is complete, this
modified parameter set must either be written
permanently to the controller via NVRAM ( see Section
8.3 “Nonvolatile RAM (NVRAM)”), or alternatively, it

can be sent every time the system is powered on. Both
the PICkit Serial Analyzer and the master I2C controller
can be used for this purpose.

Note 1: All RX/TX are remappable. Refer to Section 5.6 “Sensor Layout Configuration” for further
information.
2: The metal plate at the bottom of the device is not connected to any pins and it is recommended to
be connected to VSS externally.
