CONFIGURATION AND SETUP
The MTCH6301 is pre-configured for a 12 Receiver
(RX)/9 Transmitter (TX) touch sensor, mapped as
shown in Section 4.0 “Layout”. 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.
Once the development process is complete, these
modified parameters must either be written permanently to the controller (via NVRAM, refer to
Section 7.3 “Non-Volatile RAM (NVRAM)”), or alternatively can be sent every time the system is powered
on. Either the PICkit Serial Analyzer or the Master I2C
Controller can be used for this purpose.
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.

Touch Sensor Design
Please refer to the mTouch Sensing Solution design
center at www.microchip.com/mtouch for additional
information regarding design and layout of touch
sensors.
4.3
Sensor Layout Configuration
To properly configure a sensor from a physical layout
standpoint, the following registers must be correctly
configured:
• RX Pin Map/TX Pin Map
• RX Scaling Coefficient/TX Scaling Coefficient
• Flip State
DS41663A-page 6
4.3.1
RX/TX PIN MAP
By default, the RX and TX pins are set as shown in the
Typical Application Circuit (Figure 4.1). If you require a
different layout or a different amount of sensor channels, the RX and TX pins are configured via pin map
arrays. To access these arrays, reference Section 5.0
“Communication Protocol” and Section 6.0 “Memory Map” of this document.
The RX and TX lines are configurable for the purpose
of making trace routing and board layout more convenient. Please note that while RX pins can be used as
TX pins instead, a single pin cannot be used as BOTH
an RX and a TX channel concurrently. The pin maps
are comprised of “Pin Map ID” numbers, which are
shown in Table 4-1.

Scaling coefficient registers exist in RAM for each axis
(RX/TX) and must be modified in accordance with the
number of channels that are in use. Special attention
must be paid to sensor dimensions that have fewer
than 5 channels, which will have a smaller maximum
touch output value (coordinate).
The relationship between these constant, as well as the
maximum coordinates that will be transmitted are
displayed in Table 4-2.

Layout
An example 4-channel RX/11-channel TX sensor is
shown in Figure 4-3. In addition to using a completely
modified pin layout, this example differs from the
default configuration by also having the TX axis along
the bottom (X) and RX axis along the side (Y). Note that
some RX pins are used as TX lines in this example.

5.1
COMMUNICATION PROTOCOL
Command Protocol
Overview
All other commands are invoked by the I2C master
controller. Commands are used for configuring and
controlling the device.
The MTCH6301 has two basic communication types:
Touch & Gesture Protocol, and Command Protocol.
Master Read Details
Please note that any read from the controller by the
master, including both touch & gesture protocol and
command protocol, will be prefixed by a single byte.
This single byte denotes the number of bytes that are
to be transferred. This byte is NOT represented in the
tables and figures for the protocol, but is detailed in
Figure 5-6 and Figure 5-7.
Touch & Gesture Protocol
Fully processed touch coordinates and gestures will be
transmitted immediately as they are processed by the
MTCH6301. Since it is a slave device, the INT pin will
be asserted whenever one of these packets is ready for
transmission. This requires the master controller to initiate a READ command to receive the touch or gesture
packet.
5.2
Touch Protocol
The packet in Table 5-1 is transmitted for each touch
that is present on the sensor.

Gesture Protocol
The packet in Table 5-2 is transmitted whenever a gesture is performed on the sensor. This feature can be
enabled via the Gesture Protocol register (Table 5-2).
Gestures are NOT enabled by default.
Note:
For any “hold” gestures, packets are sent
continuously until the gesture (touch) is
released.

MANUFACTURING TEST
Please note that:
The manufacturing test ensures electrical functionality
of the sensor. This test performs the following checks
on all mapped sensor pins: short to VDD, Short to GND,
and pin-to-pin short.
1.
2.
The RX7/RX8 pins will always report an error.
If the sensor has more than 16 TX channels,
then channels 17 and 18 will never report an
error.
If an I/O error is reported, bits for the pins in question
will be set in the “TX Short Status” and “RX Short Status” registers.

I2C Specification
5.7
stretching, and this should be taken into account by the
master controller. The maximum speed at which the
MTCH6301 can operate is 400 kbps.
The MTCH6301 device supports the I2C serial protocol, with the addition of an interrupt pin for notifying the
master that data is ready. The device operates in Slave
mode, meaning that the device does not generate the
serial clock.
5.7.1
5.7.3
SERIAL DATA (SDA)
The Serial Data (SDA) signal is the data signal of the
device. The value on this pin is latched on the rising
edge of the SCL signal when the signal is an input. With
the exception of the START (RESTART) and STOP
conditions, the high or low state of the SDA pin can only
change when the clock signal on the SCL pin is low.
During the high period of the clock, the SDA pin’s value
(high or low) must be stable. Changes in the SDA pin’s
value while the SCL pin is HIGH will be interpreted as
a START or a STOP condition.
5.7.2
INTERRUPT (INT)
This pin is utilized by the MTCH6301 to signal that data
is available, and that the master controller should
invoke a MASTER READ. INT is an active high pin, and
is held low during all other activities.
Note:
5.7.4
If the device is not read within 25 ms of
asserting the INT pin, it will time out and
data will no longer be available.
DEVICE ADDRESSING
The MTCH6301 7-bit base address is set to 0x25, and
is not configurable by the user. Every transmission
must be prefixed with this address, as well as a bit signifying whether the transmission is a MASTER WRITE
(‘0’) or MASTER READ (‘1’). After appending this
read/write bit to the base address, this first byte
becomes either 0x4A (WRITE) or 0x4B (READ).
SERIAL CLOCK (SCL)
The Serial Clock (SCL) signal is the clock signal of the
device. The rising edge of the SCL signal latches the
value on the SDA pin. The MTCH6301 employs clock

WAKE ON I2C
The MTCH6301 is capable of waking up upon receiving
an I2C command from the host. Note that since
wake-up time can take up to 350 µs, the controller must
resend any I2C bytes that were not acknowledged
(ACK) before continuing the transmission.
Since the controller will wake up upon a correct I2C
address match, it does not matter which command is
sent. For simplicity, the Enable Touch command is
recommended.

Gestures
should serve most applications. These parameters and
their descriptions are available in the “Gestures” section of the memory map (Section 6.0 “Memory Map”).
Single finger gestures are a fast and intuitive way to
navigate a feature rich human-machine interface. The
MTCH6301 supports 11 single finger gestures natively,
without requiring interaction from the master processor.
Tuning may be required depending on the layout of the
sensor, the time duration, and length of activation
required for your gesture supported application. The
most common defaults are already preloaded and
FIGURE 7-1:
7.2
Note:
Gestures are NOT enabled by default,
and must be enabled via the gesture
packet configuration byte in RAM (refer to
Section 6.0 “Memory Map”).
If your application requires ONLY gesture functionality,
and does not require touch coordinates, the touch
packet configuration byte (refer to Section 6.0 “Memory Map”) can be used to turn off all touch coordinate
data.
GESTURE TYPES
Sleep
Sleep functionality is enabled by default, and follows
the behavior detailed in Figure 7-2. This functionality
can be modified via the registers related to sleep.
SLP1: This delay controls how often the sensor is
scanned for a touch while in Sleep mode. Table 7-1

Upon startup, the NVRAM’s data (if present) is loaded
into the controller. If no data is available in the NVRAM,
the device defaults are loaded instead.
Please note that parameters cannot be written individually to the NVRAM. All registers will be written with
one command. See the applicable command within the

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

WARRANTIES OF ANY KIND WHETHER EXPRESS OR
IMPLIED, WRITTEN OR ORAL, STATUTORY OR
OTHERWISE, RELATED TO THE INFORMATION,
INCLUDING BUT NOT LIMITED TO ITS CONDITION,

arising from this information and its use. Use of Microchip
