INTRODUCTION
With more than four billion buttons replaced, over one billion touch solutions shipped, and over 300 patents granted or pending, Cypress
is a worldwide leader in capacitive touch technology. Touchscreens are the predominant user interface for smartphones, tablets, e-readers,
and other portable devices. Cypress offers the expertise you need at every stage of building a projected capacitive touchscreen, from
concept to mass production. We also provide the silicon, software, tools, design, and system-level experience required to get to market
quickly.
A COMPLETE RANGE OF SOLUTIONS
Whether you need simple single-touch functionality or want true multitouch with gestures, TrueTouch supports a wide range of applications.
This family of single-chip solutions works with screen sizes from 1.5 to 10.1 inches with the best charger noise immunity in the industry;
highest in-application signal-to-noise ratio (SNR); fast refresh rates; and low active power consumption. We are the world leader in small
touchscreen packages, with chips available at 3 x 3 mm. Cypress offers single layer sensors with multitouch and two-touch capabilities for
thin, cost-effective devices. TrueTouch also supports multiple materials and stackup options for exibility in design, including PET, glass, and
metal mesh. Supported stackup types include sensor-on-lens, direct lamination, and display integrated solutions like in-cell and on-cell.
RISE ABOVE THE NOISE - SILENCE THE COMPETITION
Today’s touchscreen devices face tough environments. With form factors becoming thinner, chargers and displays becoming noisier, and
consumers using their devices in harsher conditions, providing high touch performance demands a tougher touchscreen controller.
Cypress is the worldwide leader in touchscreen performance in the presence of noise. Gen5, the newest touchscreen controller solution
from TrueTouch, leverages the industry’s broadest IP portfolio to deliver a user experience unmatched by anything on the market today:

TrueTouch ONE-OF-A-KIND NOISE SOLUTIONS
Charger Armor™
Charger Armor™ pulls the plug on charger noise. Noise enters the
touchscreen system through a power supply, such as a mobile
handset’s battery charger, during the presence of touch.
The mobile device industry has established EN standards for
maximum charger noise. TrueTouch easily exceeds these
standards. However, for chargers that can emit noise at 20 times
the spec and beyond, we have Charger Armor. It’s an adaptive
technology that listens for charger noise and activates when it
surpasses a preset threshold to effectively deal with both periodic
and broadband noise. The result is truly revolutionary charger noise
immunity to the market.
Display Noise Cancellation
LCD displays are inherently noisy. This makes it difcult for
touchscreen sensors to accurately read and interpret touch input.
TrueTouch controllers can deliver external display synchronization,
eliminating the need for air gaps or shield layers to protect
against noise. This makes TrueTouch the ideal solution for all types
of stackups, including in-cell, on-cell, and direct lamination.
SOLUTIONS FOR EVERY DEVICE
TrueTouch features support many different designs. From support for a wide range of screen sizes to true single-layer touchscreen sensors
and advanced features like waterproong, hover, and 1 mm passive stylus, Cypress has the right technology for your needs.
In addition to offering touchscreen solutions that provide industry-leading performance and features, Cypress is here to help designers
bring multitouch to the masses with an unmatched portfolio of low-cost solutions. Whether your design calls for the high-performance
Gen4 family, a low-cost Gen2 device, or something in between, Cypress has the right solution for your needs. TrueTouch also delivers the
premier single-layer sensor solution with our SLIM® sensor, which enables unbelievably thin multinger designs with TrueTouch.

CYPRESS PRODUCT SELECTOR GUIDE
SLIM® - For The Thinnest Devices Yet
Our SLIM (Single-Layer Independent Multitouch) sensor takes Cypress’s ground-breaking touchscreen innovation to a new level. The
world’s rst true single-layer multitouch sensor is a unique solution that delivers full multitouch functionality at half the thickness and cost,
allowing designers to create innovative new products. SLIM does something truly revolutionary – it enables the lowest manufacturing cost,
thinnest bezel, and thinnest stackup of any multitouch all-points touchscreen sensor module. Even with only one sensor layer, SLIM delivers
excellent accuracy and signal-to-noise ratio, and best-in-class active power.
Screen Size Support
We have expanded our position as a leader in the small-screen market as the rst company to deliver a single-chip controller exclusively
for large screens. TrueTouch controllers can support everything from the tiny 1.5” screen on an MP3 player all the way up to a
10.1” notebook display, with the same high performance you’ve come to expect from Cypress.
Advanced Features
TrueTouch supports the most advanced touchscreen functionality. A state-of-the-art touchscreen system
with a awless user interface experience involves much more than just being able to reliably detect
a nger touch. Thanks to our unique use of self and mutual capacitance sensing on the same chip,
TrueTouch provides an unmatched feature set, that includes true waterproong, hover, 1 mm passive
stylus support, proximity detection, and glove functionality.
TrueTouch controllers enable real waterproong, with end-customer products that meet stringent IP-67
standards in production today. Water on a touchscreen typically causes false touches and poor
accuracy. Cypress delivers both water rejection and wet nger tracking to ensure normal operation in
the presence of rain, mist, or sweat.
DualSense’s self plus mutual capacitance sensing also enables the touchscreen controller to sense
very small touches. Hover allows TrueTouch to accurately track a user’s nger while hovering up to
10 mm above the surface. This unique technology allows UI designers to enable useful features like
mouse-over capability, and screen magnication, and create exciting new possibilities for gaming
and 3D displays.
Mobile device owners are no longer forced to use a bulky,
inconvenient capacitive stylus; TrueTouch supports a 1 mm
passive stylus for accurate handwriting and character capture and precise navigation. TrueTouch
also delivers simultaneous palm and nger rejection capability, so you can use the stylus naturally
without discomfort or false touches. And it uses Cypress’s industry-leading, proprietary 10 V Tx and
multi-phase Tx technology to accurately sense signal input from a small passive stylus.

KEY APPLICATIONS
Mobile phones, tablet and notebook PCs, GPS navigation devices, digital still and video cameras, portable
media players, e-readers, automotive infotainment displays, printers, white goods
Capacitive proximity sensing from TrueTouch eliminates the need for separate, expensive infrared
proximity sensors, delivering better performance while drastically lowering system cost. Built-in
capacitive proximity sensing allows the touchscreen to detect your face as you bring the phone to
your ear, from up to 25 mm away. Once the touchscreen controller senses your cheek, it disables
touch detection to prevent accidental touches. It also turns off the
display to save power while you’re on the call, saving battery life.
TrueTouch can deliver real performance with gloves – even thick leather or ski gloves. Cypress’s patented
DualSense self plus mutual capacitance sensing technology, combined with the industry’s highest signal-
to-noise ratio (SNR), combine to deliver the robust signal acquisition needed for true glove support. With
1 mm accuracy and linearity, you can still rely on accurate touch input even in a bulky glove. TrueTouch
supports full 10-nger touch functionality with thinner nylon or cotton gloves, and enables two-nger touch
with gestures for thick gloves.
