DEVICE OVERVIEW
The Microchip mTouch™ MTCH810 Haptics feedback
controller provides an easy way to add tactile feedback
to any application. The device implements all the digital
functions for a Haptics feedback system. The Haptic
effects are designed to provide feedback for a “Button
and Slider” type capacitive touch interface. When
combined with an analog power driver and an Eccentric
Rotating Mass (ERM) style actuator, the resulting
circuit comprises a complete tactile feedback Haptic
system.
The device is controlled through an I2C slave interface.
In response to a two-byte command, the MTCH810 (in
combination with the driver and ERM) generates one of
13 different Haptic vibration effects. The effects are
180-220 Hz vibrations with different amplitude
envelopes and durations. The effects create a variety
of different ‘feels’ to provide feedback for different
capacitive touch commands, status and error
conditions. Several effects are similar with different
power levels in order to allow the users to compensate
for the variations in the coupling of the vibrations to the
user’s finger tip.
Two additional commands allow the termination of an
effect early and the ability to read the effects table
revision.

Pin Description
DR1
This is the enable/non-inverting digital PWM Haptics
drive output. It should be connected to the
non-inverting input of a Haptic power driver circuit
design for ERM actuators. The PWM output should
only be active when an effect is in progress.
1.4.2
DR2
This is the inverting digital PWM Haptics driver output.
It should be connected to the inverting input of a Haptic
power driver circuit designed for ERM actuators. The
PWM output should only be active when an effect is in
progress.
1.4.3
I2C – SERIAL DATA PIN (SDA)
The SDA pin is the serial data pin of the I2C interface.
The SDA pin is used to write or read the registers and
Configuration bits. The SDA pin is an open-drain Nchannel driver. Therefore, it needs an external pull-up
resistor from the VDD line to the SDA pin. Except for the
Start and Stop conditions, the data on the SDA pin must
be stable during the high period of the clock. The high
or low state of the SDA pin can only change when the
clock signal on the SCL pin is low. Refer to
Section 2.1.2 “I2C Operation” for more details on the
I2C serial interface communication.
1.4.4
I2C – SERIAL CLOCK PIN (SCL)
The SCL pin is the serial clock pin of the I2C interface.
The I2C interface only acts as a slave and the SCL pin
accepts only external serial clocks. The input data from
the master device is shifted into the SDA pin on the
rising edges of the SCL clock, and the output from the
device occurs at the falling edges of the SCL clock. The
SCL pin is an open-drain N-channel driver. Therefore, it
needs an external pull-up resistor from the VDD line to
the SCL pin. Refer to Section Section 2.1.2 “I2C Operation” for more details on I2C serial interface communication. For more details, see Figure 1-1 and Table 1-1.
DS41672A-page 3
MTCH810
1.4.4.1
1.6
Clock Stretching
A feature of the SCL pin is clock stretching. This allows
the I2C slave to hold communications at the end of
each byte from the master. Its purpose is to allow the
slave sufficient time to process the data before the next
byte is sent. It accomplishes the clock hold by turning
on the open-drain output, holding the clock line low.
This prevents the master from starting the transmission
of the next byte in the packet. For proper operation, the
I2C master must be capable of recognizing a clock
stretch condition, and suspending transmission until
the MTCH810 releases the SCL pin.
Note:
1.5
The MTCH810 includes a time-out
function on the clock stretching function
that will reset the I2C interface in the event
that the I2C interface hangs in a clock
stretch condition.
Haptic Commands
The commands are transmitted via the I2C serial
interface as a Start condition, address plus write bit,
two successive bytes and a Stop condition. For the
effect table revision number, the Write command is
followed by an I2C read of two bytes. Table 2-2 and
Table 2-3 list all the commands supported by the
MTCH810.
Hardware
To build a complete Haptic system, the two digital PWM
outputs must be filtered to produce a DC drive signal,
and amplified to produce a minimum of 300 mA of drive
at 3V. This output is then used to drive an ERM actuator. Figure 1-1 below shows a typical controller, driver
and actuator combination for a Haptic system.
The MTCH810 is the controller in the system,
accepting I2C commands and generating the
appropriate PWM signals to create the Haptic effect.
The outputs from the MTCH810 are then filtered and
amplified by the DRV8601. The amplifier stage is
essentially an audio frequency amplifier configured for
differential inputs and outputs. The output of the
amplifier then drives the ERM.
The RC network in the feedback path provides a pole
in the transfer function at 160 Hz to roll off the high
frequency gain and attenuate the ripple at the PWM
frequency. The connection between the DR1 output
and the enable of the amplifier allows the controller to
generate an output for the ERM with a drive/coast
format, rather than a drive/brake control. Using a
differential output eliminates the need for a large
capacitor on the output to AC couple the drive signal to
the ERM.
Note:
Any audio frequency drive circuits will
work in the application, provided it can
supply 300 mA at 3V and turn on in less
than 1 mS. Amplifiers with built-in “click
and pop” elimination have soft-start
enables which have a turn on time of >10
mS and are not suitable for a Haptic driver.

manufacturers.

I2C™ SERIAL INTERFACE
2.0
This device supports the I2C serial protocol. The I2C
module operates in Slave mode, so it does not
generate the serial clock.
2.1
Overview
2
This I C interface is a two-wire interface. Figure 2-1
shows a typical I2C Interface connection.
The I2C interface specifies different communication bit
rates. These are referred to as Standard, Fast or High
Speed modes. The MTCH810 device supports these
three modes. The bit rates of these modes are:
• Standard mode: Bit Rates up to 100 kbit/s
• Fast mode: Bit Rates up to 400 kbit/s
A device that sends data onto the bus is defined as a
transmitter, and a device receiving data is defined as a
receiver. The bus has to be controlled by a master
device which generates the serial clock (SCL), controls
the bus access and generates the Start and Stop
conditions. The MTCH810 device works as slave. Both
master and slave can operate as transmitter or
receiver, but the master device determines which mode
is activated. Communication is initiated by the master
(microcontroller) which sends the Start bit, followed by
the slave address byte. The first byte transmitted is
always the slave address byte, which contains the
device code, the address bits and the R/W bit.

The I2C serial protocol only defines the field types, field
lengths, timings, etc. of a frame. The frame content
defines the behavior of the device. For details on the
frame content (commands/data) refer to Section 2.3
“I2C Commands”.
Refer to the NXP User Manual (UM10204_3) for more
details on the I2C specifications.
2.1.1
SIGNAL DESCRIPTIONS
The I2C interface uses up to two pins (signals). These
are:
• SDA (Serial Data) (see Section 1.4.3 “I2C –
Serial Data Pin (SDA)”)
• SCL (Serial Clock) (see Section 1.4.4 “I2C –
Serial Clock Pin (SCL)”)
2.1.2
I2C OPERATION
The MTCH810 device I2C module is compatible with
the NXP I2C specification. The following lists some of
the module’s features:
• 7-bit Slave Addressing
• Supports Three Clock Rate modes:
- Standard mode, clock rates up to 100 kHz
- Fast mode, clock rates up to 400 kHz
• Support Multi-Master Applications
The I2C 10-bit addressing mode is not supported.
The NXP I2C specification only defines the field types,
field lengths, timings, etc. of a frame. The frame
content defines the behavior of the device. The frame
content for this device is defined in Section 2.3 “I2C
Commands”.
2.1.3
I2C BIT STATES AND SEQUENCE
Figure 2-8 shows an I2C 8-bit transfer sequence, while
Figure 2-7 shows the bit definitions. The serial clock is
generated by the master. The following definitions are
used for the bit states:
• Start bit (S)
• Data bit
• Acknowledge (A) bit (driven low)/
No Acknowledge (A) bit (not driven low)
• Repeated Start bit (Sr)
• Stop bit (P)
2.1.4
START BIT
The Start bit (see Figure 2-2) indicates the beginning of
a data transfer sequence. The Start bit is defined as the
SDA signal falling when the SCL signal is high.

REPEATED START BIT
The Repeated Start bit (see Figure 2-5) indicates that
the current master device wishes to continue
communicating with the current slave device without
releasing the I2C bus. The Repeated Start condition is
the same as the Start condition, except that the
Repeated Start bit follows a Start bit (with the Data bits
+ A bit) and not a Stop bit.
STOP BIT
The Stop bit (see Figure 2-6) indicates the end of the
I2C data transfer sequence. The Stop bit is defined as
the SDA signal rising when the SCL signal is high.
A Stop bit resets the I2C interface of the MTCH810
device.

FIGURE 2-5:
Aborting a Transmission
If any part of the I2C transmission does not meet the

accomplished with a Start or Stop condition. This is
done so that noisy transmissions (usually an extra Start
or Stop condition) are aborted before they corrupt the
device.

I2C COMMANDS
2.3
2.3.2
2
The I C protocol does not specify how commands are
formatted, so this section specifies the MTCH810
device I2C command formats and operation.
REVISION AND CONTROL
COMMANDS
The supported commands are shown in Table 2-2 and
Table 2-3.
Revision and Control commands are used to either
retrieve the current revision of the effects table within
the controller, or to terminate early a Haptic effect. Just
like the Effect commands, the command codes are
two’s compliments of one another. The Terminate-early
command is executed at the completion of the I2C Stop
condition. When the Revision command is sent, the
controller then formats the revision data and waits for
an I2C read from the master.
2.3.1
2.3.3
The commands can be grouped into the following
categories:
• Effect Commands
• Revision and Control Commands
EFFECT COMMANDS
Effect commands are used to initiate a specific Haptic
effect. The command consists of two bytes which are
the XOR of one another. The effect begins with the
completion of the I2C Stop condition.
ABORTING A COMMAND
TRANSMISSION
A Restart or Stop condition in an expected data bit
position will abort the current command sequence and
data will not be written to the MTCH810. Write
commands are automatically aborted if the binary XOR
checksum is not valid.
2.3.4
WRITE COMMAND
(NORMAL AND HIGH VOLTAGE)
The format of the command is shown in Figure 2-10.
The MTCH810 generates the A / A bits.
A Write command will only start a write cycle after a
properly formatted Write command has been received
and the Stop condition has occurred.

2.3.5
REVISION COMMAND
2.3.5.1
The format of the Revision command (see Figure 2-11)
includes the Start condition, I2C control byte (with R/W
bit set to 0), A bit, the first command byte, A bit, followed by the two’s compliment of the command byte, a
Repeated Start bit, I2C control byte (with R/W bit set to
1) and the MTCH810 device transmitting the requested
data bytes one at a time, until the master sends a Stop
condition.
Ignoring an I2C Transmission and
“Falling Off” the Bus
The MTCH810 device expects to receive complete,
valid I2C commands and will assume that any
command not defined as a valid command is due to a
bus corruption and will enter a passive high condition
on the SDA signal. All signals will be ignored until the
next valid Start condition and control byte are received.
The I2C control byte requires the R/W bit to be equal to
a logic one (R/W = 1) in order to generate a read
sequence. The data read will start with the Most Significant Byte (MSB) of the revision date and automatically
increment to the next byte after each byte request. The
sequence is ended with the master generating a Stop
or Restart condition. Figure 2-11 shows the waveforms
for a single read.

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
