1.0 THEORY OF OPERATION:
ELECTRICAL NEAR-FIELD
(E-FIELD) SENS ING
Microchip’s GestIC is a 3D sensor technology which
utilizes an electric field (E-field) for advanced proximity
sensing. It allows realization of new user interface
applications by detection, tracking and classification of
a user’s hand gestures in free space.
E-fields are generated by electrical charges and
propagate three-dimensionally around the surface,
carrying the electrical charge.
Applying direct voltages (DC) to an electrode results in
a constant electric field. Applying alternating voltages
(AC) makes the charges vary over time and thus, the
field. When the charge varies sinusoidal with frequency
f, the resulting electromagnetic wave is characterized
by wavelength λ = c/f, where c is the wave propagation
velocity — in vacuum, the speed of light. In cases
where the wavelength is much larger than the electrode
geometry, the magnetic component is practically zero
and no wave propagation takes place. The result is
quasi-static electrical near field that can be used for
sensing conductive objects such as the human body.
Microchip’s GestIC technology uses transmit (Tx)
frequencies in the range of 100 kHz which reflects a
wavelength of about three kilometers. With electrode
geometries of typically less than fourteen by fourteen
centimeters, this wavelength is much larger in
comparison. GestIC systems work w/o wave
propagation.
In case a person’s hand or finger intrudes the electrical
field, the field becomes distorted. The field lines are
drawn to the hand due to the conductivity of the human
body itself and shunted to ground. The three-
dimensional electric field decreases locally. Microchip’s
GestIC technology uses a minimum number of four
receiver (Rx) electrodes to detect the E-field variations
at different positions to measure the origin of the
electric field distortion from the varying signals
received. The information is used to calculate the
position, track movements (MGC3130) and to classify
movement patterns (gestures, MGC3X30).
Figure 1-1 and Figure 1-2 show the influence of an
earth-grounded body to the electric field. The proximity
of the body causes a compression of the equipotential
lines and shifts the Rx electrode signal levels to a lower
potential which is measured.

MGC3030/3130
1.1 GestIC Technology Benefits
GestIC E-field sensors are not impacted by
ambient influences such as light or sound, which
have a negative impact to the majority of other 3D
technologies.
GestIC technology allows gesture/position track-
ing processing on chip – no host processing
needed. Algorithms are included in the Colibri
gesture suite which runs on chip and is provided
my Microchip.
The GestIC technology has a high immunity to
noise, provides high update rates and resolution,
low latency and is also not affected by clothing,
surface texture or reflectivity.
A carrier frequency in the range of 44-115 kHz is
being used with the benefit of being outside the
regulated radio frequency range. In the same
manner, GestIC is not affected by radio
interference.
Usage of thin low-cost materials as electrodes
allow low system cost at slim industrial designs.
The further use of existing capacitive sensor
structures such as a touch panel’s ITO coating
allow additional cost savings and ease the
integration of the technology.
Electrodes are invisible to the users’ eye since
they are implemented underneath the housing
surface or integrated into a touch panel’s ITO
structure.
GestIC works centrically over the full sensing
space. Thus, it provides full surface coverage
without any detection blind spots.
Only one GestIC transmitter electrode is used for
E-field generations. The benefit is an overall low
power consumption and low radiated EMC noise.
Since GestIC is basically processing raw
electrode signals and computes them in real time
into pre-processed gestures and x, y, z positional
data, it provides a highly flexible user interface
technology for any kind of electronic devices.

2.0 FEATURE DESCRIPTION
2.1 Gesture Definit ion
A hand gesture is the movement of the hand to express
an idea or meaning. The GestIC® technology
accurately allows sensing of a user’s free space hand
motion for contact free position tracking, as well as 3D
gesture recognition based on classified movement
patterns.
2.2 GestIC Library
MGC3X30 is being provided with a GestIC Library
loader which is stored on the chip’s Flash memory.
Using this loader, a GestIC Library can be flashed on
the MGC3X30 via I2C™ with (e.g., Aurea GUI) (see
Section 7.1 “Aurea Software Package”) or an
embedded host controller. The GestIC Library
includes:
Colibri Suite: Digital Signal Processing (DSP)
algorithms and feature implementations.
System Control: MGC3X30 hardware control
features such as Analog Front End (AFE) access,
interface control and parameters storage.
Library Loader: GestIC Library update through the
application host’s interface.
2.2.1 COLIBRI SUITE
The Colibri Suite combines data acquisition, digital
signal processing and interpretation.
The Colibri Suite functional features are illustrated in
Figure 2-1 and described in the following sections.
FIGURE 2-1: COLIBRI SUITE CORE
ELEMENTS
2.2.1.1 Position Tracking (MGC3130)
The Colibri Suite’s Position Tracking feature provides
three-dimensional hand position over time and area.
The absolute position data is provided according to the
defined origin of the Cartesian coordinate system (x, y,
z). Position Tracking data is continuously acquired in
parallel to Gesture Recognition. With a position rate of
up to 200 positions/sec., a maximum spatial resolution
of 150 dpi is achieved.
2.2.1.2 Gesture Recognition (MGC3X30)
The Colibri Suite’s gesture recognition model detects
and classifies hand movement patterns performed
inside the sensing area.
Using advanced stochastic classification based on
Hidden Markov Model (HMM), industry best gesture
recognition rate is being achieved.
The Colibri Suite includes a set of predefined hand
gestures which contains flick, circular and symbol
gestures as the ones outlined below:
Flick gest ures
FIGURE 2-2: FLICK GESTURES
A flick gesture is a unidirectional gesture in a quick
flicking motion. An example may be a hand movement
from West to East within the sensing area, from South
to North, etc.
Circular gestures
FIGURE 2-3: CIRCLE GESTURES
A circular gesture is a round-shaped hand movement
defined by direction (clockwise/counterclockwise)
without any specific start position of the user’s hand.
Two types of circular gestures are distinguished by
GestIC technology:
1. Discrete Circles
Discrete Circles are recognized after performing a
hand movement inside the sensing area. The
recognition result (direction: clockwise/
counterclockwise) is provided after the hand movement
stops or the hand exits the detection area. The Discrete
Circles are typically used as dedicated application
control commands.

2. AirWheel
An AirWheel is the recognition of continuously-
performed circles inside the sensing area and provides
information about the rotational movement in real time.
It provides continuously counter information which
increments/decrements according to the movement’s
direction (clockwise/counterclockwise). The AirWheel
can be adjusted for convenient usage in various
applications (e.g., volume control, sensitivity
adjustment or light dimming).
•S
ensor Touch Gestures
FIGURE 1: SENSOR TOUCH
GESTURES
A Sensor Touch is a multi-zone gesture that reports up
to five concurrently-performed touches on the system’s
electrodes.
The Sensor Touch provides information about touch
and tapping:
1. Touch
The Sensor Touch indicates an event during which a
GestIC electrode is touched. This allows distinction
between short and long touches.
2. Tap and Double Tap
The Tap and Double Tap signalize short taps and
double taps on each system electrode. The tap length
and double tap interval are adjustable.
- Single Tap Delay: A single tap is detected
when touching the surface of an electrode
first and after the hand is pulled out of the
touch area. The Single Tap is only detected
when the timing between the touch and the
release of the touch event is smaller than the
adjusted delay. Increasing the time allows the
user more time to perform the tap. The range
for the adjusted delay can be between 0s and
1s.
- Double Tap Delay: The double tap is detected
when two taps are performed within the
adjusted delay. The range for the adjusted
delay can be between 0s and 1s. The smaller
the selected delay is, the faster the two taps
have to be executed.

The Gesture Port enables a flexible mapping of Colibri
Suite feature events to certain output signals at
dedicated pins of the MGC3X30. The individual feature
events can be mapped to one of five EIO Pins and
trigger a variety of signal changes (Permanent high,
Permanent low, Toggle, Pulse (100 ms), High Active,
Low Active). The Gesture Port simplifies and enhances
embedded system integration. It enables host-free
integration based on EIOs.

2.2.1.4 Approach Detection
FIGURE 3: APPROACH DETECTION
Approach Detection is an embedded power-saving
feature of Microchip’s Colibri Suite. It sends MGC3X30
to Sleep mode and scans periodically the sensing area
to detect the presence of a human hand.
Utilizing the in-built Self Wake-up mode, Approach
Detection alternates between Sleep and Scan phases.
During the Scan phases, the approach of a human
hand can be detected while very low power is
consumed. For more details, please see
Section 4.2.4.3 “Self Wake-up Mode”.
A detected approach of a user exceeding configured
threshold criteria will alternate the MGC3X30 from Self
Wake-up to Processing mode or even the application
host in the overall system.
Within the Approach Detection sequence, the following
scans are performed:
Approach Scan: An Approach scan is performed
during the scan phase of the MGC3X30’s Self
Wake-up mode. Typically, one Rx channel is
active but more channels can be activated via the
GestIC Library. The time interval (Scan Interval)
between two consecutive Approach scans is
configurable. For typical applications, the scan
cycle is in a range of 20 ms to 150 ms. During the
Approach scan, the activated Rx channels are
monitored for signal changes which are caused
by, for example, an approaching human hand and
exceeding the defined threshold. This allows an
autonomous wake-up of the MGC3X30 and host
applications at very low-power consumption.
Calibration Scan(1): The Approach Detection
feature includes the possibility to perform
additional Calibration scans for the continuous
adaptation of the electrode system to
environmental changes.
A Calibration scan is performed during the scan
phase of the MGC3X30’s Self Wake-up mode.
Five Rx channels are active to calibrate the
sensor signals. The Calibration scan is usually
performed in configurable intervals from 2s to
1024s.
To reduce the power consumption, the number of
scans per second can be decreased after a
certain time of non-user activity. Colibri Suite
provides a full user flexibility to configure the
starting Calibration Scans rate (Calibration Start
Scan Interval), non-user activity time-out
(Calibration Transition Time) and the Calibration
scans rate (Calibration Final Scan Interval) which
will be used afterwards. A typical implementation
uses Calibration scans every 2s during the first
two minutes, and every 10s afterwards, until an
approach is detected.
The timing sequence of the Approach Detection feature
is illustrated in Figure 2-5.

3.0 SYSTEM ARCHITECTURE
MGC3X30 are mixed-signal configurable controllers.
The entire system solution is composed of three main
building blocks (see Figure 3-1):
MGC3X30 Controller
GestIC® Library
External Electrodes
3.1 MGC3X30 Controller
The MGC3X30 feature the following main building
blocks:
Low Noise Analog Front End (AFE)
Digital Signal Processing Unit (SPU)
Communication Interfaces
The MGC3X30 provide a transmit signal to generate
the E-field, conditions the analog signals from the
receiving electrodes and processes these data digitally
on the SPU. Data exchange between the MGC3X30
and the host is conducted via the controller’s
communication interface or the Gesture Port. For
details, please refer to Section 4.0 “Functional
Description”.
3.2 GestIC® Library
The embedded GestIC Library is optimized to ensure
continuous and real-time free-space Gesture
Recognition and Motion tracking (MGC3130)
concurrently. It is fully-configurable and allows required
parameterization for individual application and external
electrodes.
3.3 External Electrodes
Electrodes are connected to MGC3X30. An electrode
needs to be individually designed following the guide
lines from the ‘GestIC Design Guide’ for optimal E-field
distribution and detection of E-field variations inflicted
by a user.

The hand Position Tracking and Gesture Recognition
capabilities of a GestIC system depends on the

The Rx and Tx electrodes in a GestIC electrode system
build a capacitance voltage divider with the
capacitances CRxTx and CRxG which are determined by
the electrode design. CTxG represents the Tx electrode
capacitance to system ground driven by the Tx signal.
The Rx electrode measures the potential of the
generated E-field. If a conductive object (e.g., a hand)
approaches the Rx electrode, CH changes its
capacitance. This minuscule change in the femtofarad
range is detected by the MGC3X30 receiver.
The equivalent circuit formula for the earth-grounded
circuitry is described in Equation 3-1.
EQUATION 3-1: ELECTRODES
EQUIVALENT CIRCUIT
A common example of an earth-grounded device is a
notebook, even with no ground connection via power
supply or ethernet connection. Due to its larger form
factor, it presents a high earth-ground capacitance in
the range of 50 pF and thus, it can be assumed as an
earth-grounded GestIC system.

3.3.2 STANDARD ELECTRODE DESIGN
The MGC3X30 electrode system is typically a double-
layer design with a Tx transmit electrode at the bottom
layer to shield against device ground and thus, ensure
high receive sensitivity. Up to five comparably smaller
Rx electrodes are placed above the Tx layer providing
the spatial resolution of the GestIC system. Tx and Rx
are separated by a thin isolating layer. The Rx
electrodes are typically arranged in a frame
configuration as shown in Figure 3-3. The frame
defines the inside sensing area with maximum
dimensions of 14x14 centimeters. An optional fifth
electrode in the center of the frame may be used to
improve the distance measurement and add simple
touch functionality.
The electrodes’ shapes can be designed solid or
structured. In addition to the distance and the material
between the Rx and Tx electrodes, the shape structure
density also controls the capacitance CRXTX and thus,
the sensitivity of the system.
FIGURE 3-3: FRAME SHAPE ELECTRODES
Note: Ideal designs have low CRxTx and CRxG to
ensure higher sensitivity of the electrode
system. Optimal results are achieved with
CRxTx and CRxG values being in the same
range.

MGC3030/3130
4.0 FUNCTIONAL DESCRIPTION
Microchip Technology’s MGC3X30 configurable
controller uses up to five E-field receiving electrodes.
Featuring a Signal Processing Unit (SPU), a wide
range of 3D gesture applications are being pre-
processed on the MGC3X30, which allows short
development cycles, as no host processing is needed.
Always-on 3D sensing, even for battery-driven mobile
devices, is enabled due to the chip’s low-power design
and variety of programmable power modes. A Self
Wake-up mode triggers interrupts to the application
host reacting to interaction of a user with the device
and supporting the host system in overall power
reduction.
The MGC3X30 offers one enhanced I2C™ interface in
including SDA, SCL and TS line (EIO0) for data
exchange with a host controller.
GestIC® sensing electrodes are driven by a low-volt-
age signal with a frequency in the range of 100 kHz,
which allows their electrical conductive structure to be
made of any low-cost material. Even the reuse of exist-
ing conductive structures, such as a display’s ITO coat-
ing, is feasible, making the MGC3X30 an overall, very
cost-effective system solution.
Figure 4-1 provides an overview of the main building
blocks of MGC3X30. These blocks will be described in
the following sections.

4.1 Reset Block
The Reset block combines all Reset sources. It
controls the device system’s Reset signal (SYSRST).
The following is a list of device Reset sources:
•MCLR

4.2 Power Control and Clocks
4.2.1 POWER MANAGEMENT UNIT (PMU)
The device requires a 3.3V ±5% supply voltage at VDD.
According to Figure 4-3, the used power domains are
as follows:
VDD Domain: This domain is powered by
VDD = 3.3V ±5% (typical VDD = 3.3V). VDD is the
external power supply for EIO, wake-up logic,
WDTR and internal regulators.
VDDC Domain: This domain is powered by
VDDC = 1.8V. It is generated by an embedded low-
impedance and fast linear voltage regulator. The
voltage regulator is working under all conditions
(also during Deep Sleep mode) preserving the
MGC3X30 data context. VDDC is the internal
power supply voltage for digital blocks, Reset
block and RC oscillators. An external block
capacitor, CEFCD, is required on VCAPD pin.
VDDA Domain: This domain is powered by
VDDA = 3.0V. It is generated by an embedded low-
impedance and fast linear voltage regulator.
During Deep Sleep mode, the analog voltage
regulator is switched off. VDDA is the internal
analog power supply voltage for the ADCs and
the signal conditioning. An external block
capacitor, CEFCA, is required on VCAPA pin.
VDDM Domain: This domain is powered by
VDDM = 3.3V. VDDM is the internal power supply
voltage for the internal Flash memory. VDDM is
directly powered through VDD=3.3V.

4.2.2 POWER SUPERVISORS
During the Power-up sequence, the system is kept
under Reset condition for approximately 200 µs (Reset
delay: tRSTDLY) after the VDD =1.5V voltage is reached
(1.2V minimum). During this delay, the system Reset
will remain low and the VDD should reach typically 2V.
When the Reset delay is elapsed, the system Reset is
released (high) and the system starts the Power-up/
Time-out (tPWRT) sequence. The system start depends
on the used VDD voltage. The Power-up/Time-out
period (tPWRT) after Reset takes 36 LSO cycles. (see
Table 4-3).
The system starts when (see Figure 4-4):
Power-up/Time-out period (tPWRT) is elapsed
•V
DD = 3.3V is already reached before the end of
tPWRT timing
The power-up sequence begins by increasing the
voltage on the VDD pin (from 0V). If the slope of the VDD
rise time is faster than 4.5 V/ms, the system starts
correctly.
If the slope is less than 4.5 V/ms, the MCLR pin must
be held low, by external circuitry, until a valid operating
VDD level is reached.

4.2.3 CLOCKS
The MGC3X30 is embedding two internal oscillators,
high speed and low speed. The High-Speed Oscillator
(HSO) is factory-trimmed, achieving high accuracy.
High-S pe ed Os cill ator (HSO):
The MGC3X30 is clocked by an internal HSO running
at 22.5 MHz ±10% and consuming very low power. This
clock is used to generate the Tx signal, to trigger the
ADC conversions and to run the SPU. During Deep
Sleep mode, the HSO clock is switched off.
Low-Speed Oscillator (LSO):
This low-speed and ultra-low-power oscillator is
typically 32 kHz with a tolerance of ±10 kHz. It is used
during power-saving modes.
4.2.4 OPERATION MODES
MGC3X30 offers three operation modes that allow the
user to balance power consumption with device
functionality. In all of the modes described in this
section, power saving is configured by GestIC Library
messages.
4.2.4.1 Processing Mode
In this mode, all power domains are enabled and the
SPU is running continuously. All peripheral digital
blocks are active. Gesture Recognition and Position
Tracking require the Processing Operation mode.
4.2.4.2 Deep Sleep Mode
During the Deep Sleep mode, VDDM and VDDA are
turned off, and VDDC is still powered to retain the data
of the SPU.
The mode includes the following characteristics:
The SPU is halted
The High-Speed Oscillator is shut down
The Low-Speed Oscillator is running
The Watchdog is switched off
Host interface pins are active for wake-up
This leads to the lowest possible power consumption of
MGC3X30.
The MGC3X30 will resume from Deep Sleep if one of
the following events occurs:
External Interrupt (IRQ0) or I2C0 Start Bit
Detection
On MCLR Reset
The Deep Sleep mode can be enabled by GestIC
Library messages.
4.2.4.3 Self Wake-up Mode
The Self Wake-up mode is a Low-Power mode allowing
an autonomous wake-up of the MGC3X30 and
application host. In this mode, the MGC3X30 is
automatically and periodically alternating between
Sleep and Scan phases.
The MGC3X30’s fast wake-up, typically below 1 ms,
allows to perform scans in very efficient periods and to
maximize the Sleep phase.
The periodic Wake-up sequence is triggered by a
programmable wake-up timer running at LSO
frequency and which can be adjusted by the Approach
Detection feature.
The MGC3X30 enters the Self Wake-up mode by a
GestIC Library message or by a non-activity time-out.
Non-activity means no user detection within the
sensing area.
The MGC3X30 will resume from Self Wake-up on one
of the following events:
Wake-up timer overflow event
External Interrupt (IRQ0) or I2C0 Start Bit
detection
On MCLR or WDTR

4.2.4.4 MGC3X30 Power Profile
The MGC3X30 power profile is illustrated in Figure 4-5.
FIGURE 4-5: MGC3X30 POWER PROFILE
MGC3X30 current consumption for the different
operation modes are summarized in Tab le 4 -1.
The Self Wake-up mode current consumption depends
on the number of active channels during Self Wake-up
mode, Approach Scan and Calibration Scan repetition
period. Changing these parameters results in different
current consumption values.
TABLE 4-1: CURRENT CONSUMPTION OVERVIEW
Mode Current Consumption Conditions
Processing mode 20 mA VDD = 3.3V

200 µA VDD = 3.3V
Calibration Scan each 10s
1 Rx Channel active
Deep Sleep mode 9 µA VDD = 3.3V
Note: In Processing mode, there are always five
Rx channels activated. Choosing only four
Rx channels in Aurea does not have an
impact on the current consumption during
Processing mode.

4.3 Transmit Signal Generation
The Tx signal generation block provides a bandwidth
limited square wave signal for the transmit electrode.
Frequency hopping adjusts automatically the Tx carrier
frequency in the range of 44-115 kHz, depending on
the environmental noise conditions. GestIC Library
automatically selects the lowest noise working
frequency in case the sensor signal is compromised.
Frequencies can be enabled/disabled via the GestIC
Library.
4.4 Receive (Rx) Channels
There are five identical Rx channels that can be used
for five respective receive electrodes. Four receive
electrodes are required for Position Tracking and
Gesture Recognition. A fifth electrode can be used for
touch detection and to improve distance measurement.
Each channel has its own analog signal conditioning
stage, followed by a dedicated ADC. For specific
features such as Approach Detection, individual Rx
channels can be activated or deactivated via the
GestIC Library. According to the electrode
characteristics, the channels have to be
parameterized.
The signal conditioning block contains analog filtering
and amplification as shown in Figure 4-10.
FIGURE 4-10: SIGNAL CONDITIONING
BLOCK
For individual electrode characteristics, the Rx
channels can be configured as follows:
Signal matching: The received signal is sampled
at a sampling rate, equal to twice the Tx
frequency providing a high and low ADC sample.
The signal matching block adjusts the received
signal towards the same value of high and low
ADC samples. The offset can be adjusted
accordingly.
The matched signal output is amplified using a
programmable gain amplifier to achieve a better
sensitivity.
4.5 Analog-to-Di gital Converter (ADC)
As outlined in Section 4.4 “Receive (Rx) Channels”,
each Rx channel features a dedicated ADC with a
trigger derived from the internal clock. ADC samples
are synchronous with twice the Tx transmit frequency.
4.6 Signal Processing Unit (SPU)
The MGC3X30 features a Signal Processing Unit
(SPU) to control the hardware blocks and process the
advanced DSP algorithms included in the GestIC
Library. It provides filtered sensor data, continuous
position information and recognized gestures to the
application host. The host combines the information
and controls its application.
4.7 Parameters Storage
The MGC3X30 provides an embedded 32 kBytes Flash
memory which is dedicated for the GestIC Library and
storage of the individual configuration parameters.
These parameters have to be set according to the
individual electrode design and application. The
GestIC Library and parameters are loaded into
MGC3X30 with the provided software tools or,
alternatively, via GestIC Library messages by the
application host. For more details on the MGC3X30
tools, please refer to Section 7.0 “Development
Support”.

5.0 INTERFACE DESCRIPTION
The MGC3X30 supports an I2C™ interface with Slave
mode and the Gesture Port (five configurable EOIs).
5.1 Interface Selection
The MGC3X30 interface selection pin, IS2, is used to
select the I2C slave address. There are two different
addresses.
5.2 Extended Input Output (EIO)
The MGC3X30 provides input/output pins with
extended features. These pins are controlled by
GestIC® Library and listed in Table 5-2.
5.3 Interrupt Requests
MGC3X30 IRQ0 and IRQ1 interrupt lines are used by
the host to wake-up the MGC3X30 from Deep Sleep
and Self Wake-up modes. If a wake-up event is
detected on IRQ0 or IRQ1 lines, the MGC3X30
switches to the Processing mode.
5.4 Gesture Port
The MGC3X30 provides five output pins which can be
used to output the Colibri Suite features events. These
pins are controlled by GestIC Library to signal that an
event occurred. The host does not need to monitor the
I2C bus to get GestIC Library events, but only has to
monitor the Gesture Port pins. This feature is used in
parallel to I2C communication.
The Colibri Suite Gesture Port feature mapping is
illustrated in Figure 5-1.

The MGC3X30 Device ID 7-bit address is: 0x42
(0b1000010) or 0x43 (0b1000011) depending on the
interface selection pin configuration (IS2+IS1). Please
refer to Table 5-6.
I2C™ Master Read Bit Timing
Master read is to receive position data, gesture reports
and command responses from the MGC3X30. The
timing diagram is shown in Figure 5-4.
Address bits are latched into the MGC3X30 on
the rising edges of SCL.
Data bits are latched out of the MGC3X30 on the
rising edges of SCL.
ACK bit:
- MGC3X30 presents the ACK bit on the ninth
clock for address acknowledgment
-I
2C master presents the ACK bit on the ninth
clock for data acknowledgment
•The I
2C master must monitor the SCL pin prior to
asserting another clock pulse, as the MGC3X30
may be holding off the I2C master by stretching
the clock.
I2C™ Communication Steps
1. SCL and SDA lines are Idle high.
2. I2C master presents Start bit to the MGC3X30
by taking SDA high-to-low, followed by taking
SCL high-to-low.
3. I2C master presents 7-bit address, followed by a
R/W = 1 (Read mode) bit to the MGC3X30 on
SDA, at the rising edge of eight master clock
(SCL) cycles.
4. MGC3X30 compares the received address to its
Device ID. If they match, the MGC3X30
acknowledges (ACK) the master sent address
by presenting a low on SDA, followed by a low-
high-low on SCL.
5. I2C master monitors SCL, as the MGC3X30 may
be clock stretching, holding SCL low to indicate
that the I2C master should wait.

6. I2C master receives eight data bits (MSB first)
presented on SDA by the MGC3X30, at eight
sequential I2C master clock (SCL) cycles. The
data is latched out on SCL falling edges to
ensure it is valid during the subsequent SCL
high time.
7. If data transfer is not complete, then:
-I
2C master acknowledges (ACK) reception of
the eight data bits by presenting a low on
SDA, followed by a low-high-low on SCL.
- Go to step 5.
8. If data transfer is complete, then:
-I
2C master acknowledges (ACK) reception of
the eight data bits and a completed data
transfer by presenting a high on SDA,
followed by a low-high-low on SCL.
I2C™ Master Write Bit Timing
I2C master write is to send supported commands to the
MGC3X30. The timing diagram is shown in Figure 5-5.
Address bits are latched into the MGC3X30 on
the rising edges of SCL.
Data bits are latched into the MGC3X30 on the
rising edges of SCL.
ACK bit:
- MGC3X30 presents the ACK bit on the ninth

-I
2C master presents the ACK bit on the ninth
clock for data acknowledgment
The master must monitor the SCL pin prior to
asserting another clock pulse, as the MGC3X30
may be holding off the master by stretching the
clock.
I2C™ Communication Steps
1. SCL and SDA lines are Idle high.
2. I2C master presents Start bit to the MGC3X30
by taking SDA high-to-low, followed by taking
SCL high-to-low.
3. I2C master presents 7-bit address, followed by a
R/W = 0 (Write mode) bit to the MGC3X30 on
SDA, at the rising edge of eight master clock
(SCL) cycles.
4. MGC3X30 compares the received address to its
Device ID. If they match, the MGC3X30
acknowledges (ACK) the I2C master sent
address by presenting a low on SDA, followed
by a low-high-low on SCL.
5. I2C master monitors SCL, as the MGC3X30 may
be clock stretching, holding SCL low to indicate
the I2C master should wait.
6. I2C master presents eight data bits (MSB first) to
the MGC3X30 on SDA, at the rising edge of
eight master clock (SCL) cycles.
7. MGC3X30 acknowledges (ACK) receipt of the
eight data bits by presenting a low on SDA,
followed by a low-high-low on SCL.
8. If data transfer is not complete, then go to step
5.
9. Master presents a Stop bit to the MGC3X30 by
taking SCL low-high, followed by taking SDA
low-to-high.
5.5.2 TRANSFER STATUS LINE
MGC3X30 requires a dedicated Transfer Status line
(TS) which features a data transfer status function. It is
used by both I2C Master and Slave to control data flow.
The TS (Transfer Status) line is electrically open-drain
and requires a pull-up resistor of typically 10 k, from
TS to VDD. TS Idle state is high.
The MGC3X30 (I2C Slave) uses this line to inform the
host controller (I2C Master) that there is data available
which can be transferred. The host controller uses the
TS line to indicate that data is being transferred and
prevents MGC3X30 from updating its data buffer.
Table 5-9 shows how the TS line is used in the different
states of communication.
MGC3030/3130
DS40001667E-page 32 Advance Information 2012-2017 Microchip Technology Inc.
MGC3X30 can update the I2C buffer only when the TS
is released by both chips and a data transfer can only
be started when MGC3X30 pulls the TS low.
This procedure secures that:
the host is always informed when new sensor
data is available
buffer updates in MGC3X30 are always
completed before data is sent to the I2C bus
Figure 5-3 shows the complete communication
protocol.
FIGURE 5-3: MGC3X 30 COMMUNICATION PROTOCOL
In addition to the standard I2C interface, the
communication between MGC3X30 and the host
controller requires a proper handling of the Transfer
Status.
TABLE 5-9: USAGE OF TRANSFER STATUS LINE
MGC3X30 Host Controller TS Line Status
Released (H) Released (H) High Host finished reading data (Transfer end). No more data to
be transferred to the host. MGC3X30 is allowed to update the
data buffer.
Asserted (L) Released (H) Low Data from MGC3X30 is available to be sent, but the host has
not yet started reading. If the host is busy and did not start
reading before the next data update (5 ms), the MGC3X30
will assert the TS line high while updating the data buffer.
Asserted (L) Asserted (L) Low Host starts reading. MGC3X30 data buffer will not be
updated until the end of transfer (host releases TS high).
Released (H) Asserted (L) Low MGC3X30 is ready to update the data buffer, but the host is
still reading the previous data. MGC3X30 is allowed to
update the data only when the host releases the TS high.
Note 1: The stop condition after an I2C™ data
transmission is generated by the host
controller (I2C™ Master) after the data
transfer is completed. Thus, it is
recommended to verify the amount of
bytes to be read in the message header
(Size field).
2: Transfer Status is only needed for data
transfer from MGC3X30 to the host
controller. Writing to MGC3X30 does not
require the additional TS signal.

6.0 APPLICATION ARCHITECTURE
The standard MGC3X30 implementation is a single-
zone design. This configuration is based on one
MGC3X30 connected to an application host via I2C™
with MGC3X30 being Slave and Application Host being
Master. The following lines are needed for full I2C
communication (see Figure 6-1).
Data reporting and flow-control scenarios are
described below for I2C communication:
•SDA
•SCL
EIO0 (Transfer Status Line) is toggled indicating
that new data is available and checking whether
the host has already started data reading or not.
FIGURE 6-1: APP LICATION CIRCUITRY
6.1 ESD Considerations
The MGC3X30 provides Electrostatic Discharge (ESD)
Voltage protection up to 2 kV (HBM). Additional ESD
countermeasures may be implemented individually to
meet application-specific requirements.
6.2 Power Noise Considerations
MGC3X30 filtering capacitors are included in the
reference design schematic (Please refer to Figure 6-2).
6.3 Irradiated High-Frequency Noise
In order to suppress irradiated high-frequency signals,
the five Rx channels of the chip are connected to the
electrodes via serial 10 k resistors, as close as
possible to MGC3X30. The 10 k resistor and the
MGC3X30 input capacitance are building a low-pass
filter with a corner frequency of 3 MHz. An Additional
ferrite bead is recommended to suppress the coupling
of RF noise to the Tx channel (e.g., 600 at 100 MHz).
An additional ferrite bead is recommended to suppress
the coupling of RF noise to the Tx channel (e.g., 600
at 100 MHz).

6.5 Layout Recommendation
This section will provide a brief description of layout
hints for a proper system design.
The PCB layout requirements for MGC3X30 follow the
general rules for a mixed signal design. In addition,
there are certain requirements to be considered for the
sensor signals and electrode feeding lines.
The chip should be placed as close as possible to the
electrodes to keep their feeding lines as short as
possible. Furthermore, it is recommended to keep
MGC3X30 away from electrical and thermal sources
within the system.
Analog and digital signals should be separated from
each other during PCB layout in order to minimize
crosstalk.
The individual electrode feeding lines should be kept as
far as possible apart from each other.
VDD lines should be routed as wide as possible.
MGC3X30 requires a proper ground connection on all
VSS pins, including the exposed pad (pin 29).

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.
