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.
Applications:
• Wearable Devices such as Headphones,
Watches, Fitness Wristbands
• Track Pads and Computer Peripherals
• Input Devices with Configurable Button, Keypad
or Scrolling Functions
• Any Interface with Single-Finger Gestures to
Swipe, Scroll, or Doubletap Controls
• Home Automation Control Panels
• Security Control Keypads
• Automotive Center Stack Controls
• Gaming Devices
• Remote Control Touch Pads
Touch Sensor Support:
• Up to 15 Channels
• Sensor Sizes up to 120 mm (4.7”)
• Individual Channel Tuning for Optimal Sensitivity
• Works with Printed Circuit Board (PCB) Sensors,
Film, Glass and Flexible Printed Circuit (FPC)

Number of channels used for X axis
Number of channels used for Y axis
MTCH6102 is designed to work with sensors with a
minimum of 3x3 sensor channels, and a total maximum
of 15 channels. The number of channels on each axis
is governed by the registers in Table 6-1. For all sensor
configurations, the following conditions must be met:
1. Channel layout must start at RX0.
2. Each axis must have the associated channels in
either ascending or descending order.
3. No unconnected channel pins are allowed in the
middle of a layout.
Table 6-2 shows an example of each rule being broken
by a 6x5 sensor layout, followed by the correct layout
in the last column.

6.3 Sensor Output Resolution
MTCH6102 interpolates 64 discrete points between
each channel and 32 points past the centerline of each
edge. As a result, the maximum value in the TOUCHX
and TOUCHY registers will be
(64xNUMBEROFCHANNELS) on each axis. For the
default 9x6 sensor, this results in a maximum resolution
of 576x384.
