CYAT8168X overview
A capacitive touchscreen detects changes in capacitance to determine the location of one or more fingers on the
surface of the touchscreen. A typical touchscreen system consists of a capacitive touchscreen sensor, an FPC
bonded to the sensor, and the touchscreen controller mounted on the FPC. The FPC connects the touchscreen
controller to the host processor. Users can interact with the displayed user interface through finger movements
and gestures on the surface of the touchscreen.
CYAT8168X is a capacitive touchscreen controller with the sensing and processing technology to resolve the
locations and report the positions of up to ten fingers on the touchscreen. The touchscreen controller converts
an array of sensor capacitances into an array of digital values, which are processed by touch-detection and
position-resolution algorithms in the controller. These algorithms determine the location and signal magnitude
of each finger on the touchscreen.
Infineon provides:
• Application firmware
• Design guidance for the sensor and FPC
• Touchscreen sensor MTK
The CYAT8168X functional block diagram is shown in Figure 2. This device contains a high-performance Arm®
32-bit CPU with an integrated hardware multiply unit. This CPU controls all sensing and processing of measured
capacitance results to allow tracking and reporting touches. The controller is optimized for low power and fast
response time, with built-in support for manufacturing test. The touchscreen controller communicates with a
host through an I2C slave interface at up to 400 kbps or an SPI interface at up to 8 Mbps.
CYAT8168X collects the touchscreen sensor information using the touch subsystem. This touch subsystem
consists of a 5-V TX pump, TX drivers, RX channels, and a programmable transmit/receive (TX/RX) multiplexer.
The multiplexer electrically connects the analog front end of each RX channel and TX driver to the appropriate
row and column electrodes of the touchscreen sensor.
The controller TX/RX multiplexer allows flexibility of chip placement on the FPC. All pins connecting to the
touchscreen sensor are programmable as either TX or RX. Infineon reference documents are available under NDA
through your local Infineon sales representative. You can also direct your requests to
automotive@infineon.com.

Features overview

Features overview
3.1
AutoArmor
AutoArmor improves both electromagnetic emissions and immunity. It ensures no false finger touches when
CYAT8168X is exposed to electromagnetic waves.
3.2
Water rejection
Water droplets can cause false touches to be reported. However, CYAT8168X continues to operate in the presence
of water droplets or condensation. CYAT8168X enables water rejection using DualSense, Infineon’s patented self-
and mutual-capacitance sensing ability.
3.3
Wet-finger tracking
In a touchscreen system, moisture on fingers can cause false touches to be reported and make tracking of fingers
across the screen difficult. CYAT8168X can detect and track fingers that are wet and enable more robust
functionality of the touchscreen, using DualSense. This includes sweaty fingers touching the screen or fingers
moving across a mist-covered screen.
3.4
Glove
CYAT8168X detects and tracks gloved fingers. Glove support allows navigating the touchscreen without having
to remove gloves or without the use of expensive conductive gloves. Tracking of gloved fingers is supported by
automatic mode switching, which automatically transitions between tracking gloved fingers and other
touch-tracking modes. Ten-finger glove-touch is supported for thin gloves ( 1-mm thick) and two-finger
operation is supported for thick gloves ( 5-mm thick).
3.5
Automatic mode switching
CYAT8168X supports automatic mode switching which detects and tracks a new touch object type without
requiring manual selection of the touch type from the user. Automatic mode switching allows an uninterrupted
user experience when switching between a bare finger, gloved finger, fingernail, or wet finger.
3.6
Large finger tracking
A well-designed touchscreen system must correctly report a large finger or thumb as only a single touch. If this is
not supported, a large finger can incorrectly be reported as two or more touches, hampering the user experience.
When an object, such as a thumb, is pressed against the touchscreen sensor, CYAT8168X ensures that only one
touch is reported at the center of the object.
3.7
Large object detection and rejection
It is important to be able to detect the presence of a large object on the touchscreen sensor. Common example
is touching a palm on the screen when typing. CYAT8168X can determine the presence of a large object, such as
a fist or palm, from the touchscreen data. This presence may either be rejected or reported to the host.
3.8
Look-for-Touch
Look-for-touch is a low-power and fast-wakeup mode, in which the touchscreen sensor is measured for an
increase in self-capacitance. An increase in self-capacitance indicates that a touch is present. Because it is only
necessary to detect a finger’s presence, and not location, the sensing can be done at a much lower SNR, requiring less
time and power. Look-for-touch sensing is used to implement multiple functions, including wake-on-touch and fast
first-touch response.
3.9
Low power wake-up button
Low-power wake-up button is a special mode for one dedicated button. In this mode, the host can send
CYAT8168X to DeepSleep mode. Then, CYAT8168X regularly transitions to scan this single button. On detection
of touch on this button, a WAKE pin is set to HIGH. The system can use this signal to control power switches and
wake-up the whole system.

Infineon continues to develop additional patterns and materials to increase performance and decrease system
cost.
The specific sensor pattern used varies based on the mechanical, electrical, optical, and cost constraints; all of
these factors must be considered for an optimal solution.
For example:
• Overlays/lens thickness < 1 mm should not use SSD due to large signal disparity (SD).
• DCVCOM LCDs, with strong image-related noise, require an air gap, a shield layer, or a self-shielding pattern
such as MH3.

Power supply information

Power supply information
CYAT8168X contains five external power domains: VDDA, VDDA_Q, VDDD, VCCD, and VCCTX. VDDA supplies power
to the chip’s TX pump and drivers. VDDA_Q supplies power to the RX analog circuitry. VDDD supplies power to the
digital I/Os, core LDO regulator, supply monitors, and external reset circuitry (XRES). VCCD supplies power to the
CPU core, and may be configured as an input or output, depending on if a 1.71–1.95-V VDDD supply is used.
6.1
Required external components
The touch controller device requires external components for proper device operation. Quantities are dependent
on the power supply configuration used. External capacitors require an X5R dielectric characteristic or better. It
is recommended to use an X7R dielectric characteristic or better for high-frequency 0.1-µF/0.22-µF capacitors.
VDDA:
• 1.0-Ω, 5% tolerance resistor
• 0.1-µF capacitor
• 1-µF capacitor
VDDA_Q:
• 0.1-µF capacitor (only required on one of the VDDA_Q pins)
• Two 1.0-µF capacitors (one at each end of the package)
• 1.0-Ω, 5% tolerance resistor
VDDD:
• 1-μF capacitor if VCCD and VDDD are connected (shown in Figure 6 and Figure 7) or 0.1-μF capacitor if
VDDD 3.0 V (shown in Figure 8, Figure 9, and Figure 10).
VCCD:
• 1-µF capacitor if VCCD and VDDD are connected (shown in Figure 6 and Figure 7)
• 100-nF capacitor
VCCTX:
• 0.22-µF capacitor (configurations with the VCCTX pump enabled)

Power supply information
6.2
Voltage coefficient
The actual capacitance of external capacitors may be reduced with higher bias voltage. Check the capacitor
datasheet for the voltage coefficient. Capacitors used for power supply decoupling or filtering are operated under
a continuous DC-bias. Many capacitors used with DC power across them provide less than their target
capacitance, and their capacitance is not constant across their working voltage range. When selecting capacitors
for use with this device verify that the selected components provide the required capacitance under the specific
operating conditions of temperature and voltage used in your design. While the temperature ratings of a
capacitor are normally found as part of its catalog part number (for example, X7R, C0G, Y5V), the matching voltage
coefficient may only be available on the component datasheet or direct from the manufacturer. Use of
components that do not provide the required capacitance under the actual operating conditions may cause the
device to perform to less than the datasheet specifications.
The available power configurations, with the TX pump enabled, are shown in Figure 6 and Figure 8. Figure 7,
Figure 9 and Figure 10 show power supply configurations with the TX pump disabled.

Power States summary

Power States summary
The CYAT8168X controller has four power states, as illustrated in Figure 11:
• Active, where the touchscreen is actively scanned to determine the presence of a touch and identify the touch
coordinates.
• Active look-for-touch, where the device performs fast self-capacitive scan to determine if a touch exists.
• Low power, where the touchscreen is scanned for touch presence at a much slower rate.
• Deepsleep, where the touchscreen is not scanned and CYAT8168X is in a low power state with no processing.
The CYAT8168X controller automatically manages transitions between three power states (Active, Active
Look-for-touch, and Low Power). The host can force transition in and out of the fourth power state (Deepsleep).
The active state emphasizes low refresh time for accurate finger tracking, the active look-for-touch state allows
fast first-touch response, and the low power state enables low power consumption during periods of no touch
activity. In all three states, the CYAT8168X controller periodically scans the panel to determine the presence of a
touch. If a touch is present, the controller either enters or remains in the active state where it identifies the touch
coordinates. These tasks occur at different rates in the three states and the detection of touches affects
transitions between the states. Transition from active to active look-for-touch occurs when no touch is detected.
Host can request to disable low power thus forcing CYAT8168X controller to stay out of the Low-Power state at
all times for the fastest response to the first touch on the panel.
The following parameters configure power states, which can be configured by the host:
• Refresh interval (register ACT_INTRVL) sets the minimum time between the start of subsequent touchscreen
scans in the active state.
• Active Look-for-touch interval (register ACT_LFT_INTRVL) sets the minimum refresh time in the active
look-for-touch state.
• Active Mode Timeout (register TCH_TMOUT) sets the period of time in which no touch is detected during the
Active Look-for-touch state before transitioning to the low power state.
• Low-Power interval (register LP_INTRVL) sets the time in the low power state between touchscreen scans.
• Deep Sleep is entered via a command from the host to move the device into the Deepsleep state. Automatic
entry into the low power state is enabled by setting the LOW_POWER_ENABLE parameter.

Pin information
CYAT8168X is available in both the 128-pin TQFP and 100-pin TQFP packages. This section lists pin names,
descriptions, and mappings to the physical package. Input and output pins may have more than one possible
configuration. Guidance for each configuration option is provided below:
XY: XY pins may be configured as either transmit (TX) drive or receive (RX) sense, allowing each design to be
optimized based on the sensor pattern and layout. See PSoC™ Automotive Multitouch Touchscreen Controller
Module Design Best Practices (001-50467), for guidelines. Unused XY pins should be left unconnected. TX and
RX pins are tied to VSS internally during the Deepsleep power state.
P0/P1/P2: Unused port 0, port 1, and port 2 pins should be left unconnected.
External Reset (XRES): If the XRES pin is unused, it must be connected to VDDD (either directly or through an
external resistor).
SWD: Serial wire debug (SWD) is the recommended programming mode for all designs. If SWD is not used on the
target board, use the bootloader to upgrade firmware.
Do Not Use (DNU): DNU pins must be left unconnected to ensure proper device operation.
COMM_INT: The COMM_INT pin is required. This interrupt pin is used for the host communication. If resistive
mode is used, note that all I/Os are Hi-Z during chip initialization (after XRES or Bootloader Exit), so an additional
external resistor is recommended.
P1[0] (WAKE): Wake pin indicates the status of the low-power wake-up button.
P1[1] (HOST RESET): The Host reset pin is used to send a reset pulse to the host controller on specific predefined
conditions on the low-power wake-up button.
Pin configurations: Multiple pin configurations are supported using Touch Tuning Host Emulator (TTHE)
software. Pins are configured using the TTHE Pin Configuration Wizard.

Notes
17.These min and max limits are inclusive of noise. For proper operation, VDDA or VDDD with combined noise
cannot go below or above the specified min or max limits.
18.If minimum ramp rate cannot be met, XRES should be asserted during voltage ramp (1.5 V > VDDD > 1.0 V for
ramp-down or until voltage is stable for ramp-up). Note that a glitch on the I2C bus could occur during voltage
ramp in this case.

Important Note: The P0[0] and P0[1] pins have I/O cells optimized for use on multi-drop buses. When the touch
device is powered OFF, the pin drivers do not load the attached bus, such that other devices attached to them
may continue to communicate.
