MTCH6102
MTCH6102 Low-Power Projected Capacitive Touch Controller
Description:
Microchip’s MTCH6102 is a turnkey projected
capacitive touch controller that simplifies adding
gestures
to
touch
interface
designs
with
industry-leading low-power performance. It utilizes up
to 15 channels to support taps, swipes, and scrolling on
XY touch pads and touch screens. MTCH6102 allows
designers to quickly and easily integrate projected
capacitive touch into their cost-sensitive, low-power
application. MTCH6102 provides developers with a
flexible touch-sensing solution to optimize common
constraints of size, power and cost that are critical to
applications such as wearable devices, remote
controls, gaming devices and track pads.

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.
