DEVICE OVERVIEW
The MTCH102/5/8 provides an easy way to add
proximity or touch detection to any application with
human machine interface. These devices can integrate
up to two, five and eight capacitive touch/proximity
detection sensors which can work through plastic,
wood or even metal front panels with Microchip’s
proprietary Metal over Capacitive technology. It also
supports a wide range of conductive materials as
sensors, like copper pad on PCB, silver ink, PEDOT or
carbon printing on plastic film, Indium Tin Oxide (ITO)
pad, wire/cable, etc.
at run-time. An active-low output will communicate the
state of the sensors to a host/master MCU or drive an
indication LED.
The MTCH102/5/8 uses a sophisticated scan
optimization algorithm to actively attenuate noise from
the signal. The sensitivity adjustment and flexible
power mode allow users to easily configure the device
FIGURE 1-1:
1.1
MTCH102/5/8 BLOCK DIAGRAM
Pin Description
Guard
MTIx
Connect the sensor to this input. An additional resistor
of at least 4.7 kΩ is recommended for best noise
immunity. Sensors work best when the base
capacitance is minimized. This will maximize the
percentage change in capacitance when a finger is
added to the circuit. The recommended sensor
capacitance is 5pF to 50pF.
MTOx
The MTOx pin is an open-drain output which reports
the touch/proximity state of the corresponding MTIx
input. A pull-up resistor is required on each output. The
MTOx will pull the line low when a touch/proximity
event happens and release the line when the touch/
proximity is released.
DS40001793C-page 6
The Guard function is multiplexed with one of the MTIx
pins. If the GC pin is floating, the Guard pin will function
as a standard MTIx sensor. If the GC pin is grounded,
the Guard pin will output a signal in-phase with the
other sensors being scanned. This has several
advantages, such as providing a mutual capacitance
coupling to the sensors to increase sensitivity, and
providing a low-impedance trace near the sensor to
absorb noise. The active guard layout should encircle
the sensor and its traces so that it will shield the sensor.
For more information about guarding and layout
guidelines, see application notes “mTouch® Sensing
Solution Acquisition Methods Capacitive Voltage
Divider” (AN1478) and “Techniques for Robust Touch
Sensing Design” (AN1334).

MTCH102/5/8
GC
The GC (Guard Control) is multiplexed with one of the
MTOx pins. By grounding the GC pin, the active guard
signal will be enabled on the Guard pin.
MTSA
The MTSA pin is an input that determines the
sensitivity of touch/proximity sensors. Applying VDD will
give the lowest sensitivity while applying VSS will give
the highest.
MTPM
The MTPM pin is an input that determines the power
mode of MTCH10X devices. By connecting VSS to the
MTPM pin, the device will operate in Low-Power mode.
See Figure 5-1 for current consumption and response
time specifications. When applying VDD on the
MTCH10X MTPM pin, the device will scan the sensors
at the fastest possible sampling rate. Host-controlled
sampling rates are available using the Smart Scan
Scheduling feature described in Section 4.0, Power
Mode and Timeout Reset.

SENSITIVITY ADJUSTMENT
FIGURE 3-3:
The sensitivity of the sensor inputs determines how far
it can respond to proximity or how much capacitance is
required to activate a touch. The voltage on the
MTCH102/5/8 MTSA pin will determine the sensitivity.
VDD voltage will give the lowest sensitivity, while VSS
voltage will give the highest. The device will sample the
voltage on the MTSA pin after every 32nd scan, so it
does not only support setting a fixed sensitivity by a
resistor ladder, but it also allows adjusting the
sensitivity dynamically while the device is running. A
Digital-to-Analog Converter (DAC) controlled by the
host or a hardware potentiometer can be used to adjust
the sensitivity. Refer to the typical circuit in Figure 3-1
to Figure 3-4.

POWER MODE AND TIMEOUT
RESET
FIGURE 4-2:
The MTCH102/5/8 has three power mode options to
meet the needs of various applications: Normal mode,
Low-Power mode and Smart-Scheduling mode. The
state of the MTPM pin determines the power mode.
4.1
Burst Scan
Normal Mode
SMART-SCHEDULING
MODE
Sleep
MTIx
The device will run in Normal mode if the MTPM pin is
connected to VDD. In this mode, the MTCH102/5/8 will
scan continuously; so it will achieve the shortest
response time among the three power modes, but also
the power consumption is the highest.
Scan Interval
MTPM
4.2
Low-Power Mode
The device will run in Low-Power mode if the MTPM pin
is connected to VSS. The device will go to Sleep for
256 ms after each round of sensor scans; so it will
achieve the lowest power consumption, but it will have
the longest response time among the three power
modes, as shown in Figure 4-1.
4.4
FIGURE 4-1:
For the Normal and Low-Power modes, the timeout
duration is 10 seconds. For the Smart-Scheduling
mode, the timeout duration is 400 multiplied by the
scan interval.
Burst Scan
LOW-POWER MODE
Sleep:256ms
Timeout Reset
The device keeps track of the activated state duration
for each MTIx input channel. The sensor state will be
reset once the activated state duration exceeds the
timeout duration, and the associated MTOx pin will
release the line.
MTIx
4.3
Smart-Scheduling Mode
The MTCH102/5/8 also implements a Smart-Scheduling
mode that allows a host to set the exact sampling rate by
pulsing the MTPM pin, as shown in Figure 4-2. The
minimum recognizable pulse width is 25 ns. If the MTPM
pin is toggled during a scan cycle, the device will skip the
next Sleep and immediately start a new set of scans.

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.
