WE TOOK NOISE OUT OF THE EQUATION.
SO YOUR DESIGNS CAN BE HEARD CLEARLY IN THE MARKET.
REVOLUTIONARY TRUETOUCH TOUCHSCREEN CONTROLLERS DELIVER GAME-CHANGING
NOISE IMMUNITY, PERFORMANCE, AND INNOVATION
The world is a noisy place. Battery chargers, radio transmitters, LCDs, and
other sources can generate enough noise to wreak havoc with capacitive
touchscreen designs.
The touchscreen world is demanding larger, thinner, more sophisticated
designs, making noise a bigger challenge moving forward.
Fortunately, Cypress TrueTouch® touchscreen solutions get noise out of your
way so nothing interferes with your imagination. With the industry’s highest
signal-to-noise ratio (SNR), best waterproofing, excellent touch performance,
quickest time-to-market, and largest portfolio of proprietary noise-immunity
solutions, TrueTouch-powered devices enable a new era of touch
interaction and creativity.
With Cypress, you can develop thinner products with more innovative
interfaces that work under more challenging conditions than ever before.

to bring devices to market faster, thanks to
revolutionary noise immunity and performance.
What will you do with TrueTouch?
In addition to innovative, proprietary
noise immunity technologies (see
next page), the TMA5XX chip family
includes these features:
• All-New Analog Front End
combines narrow-band response
with high-frequency sampling and
advanced hardware DSP filtering
to deliver revolutionary charger
and display noise immunity
• Eliminates Charger Noise up
to 40 Vpp at 1-500 kHz
• The Best Gets Better: With
multi-phase TX and single-pass
correlated scanning, the industry’s
highest SNR gets even higher
• Best Waterproofing in the
World due to improved
self-capacitance sensing
and patented self- plus
mutual-capacitance architecture
• Display Integrated Design
Support for both in-cell and
on-cell stackups for thin, sleek form
factors
• 2-mm Passive Stylus Support
plus palm rejection for the ultimate

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.
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, in the presence of touch. The mobile device
industry has established EN standards for maximum
charger noise and TrueTouch easily exceeds them.
However, because many chargers can emit noise up
to 40 V peak-to-peak, we have Charger Armor. It is
an adaptive technology that listens for charger noise
and activates proprietary noise-elimination
technologies to effectively deal with both periodic and
broadband noise. The result is revolutionary charger
noise immunity to the market.
Charger Armor™ and display noise cancellation
technologies help deliver high performance from
touchscreen devices in the presence of extreme noise.

SLIMMING DOWN YOUR
BUDGET AND YOUR DESIGNS.
SIGNAL-TO-NOISE RATIOS HAVE NEVER BEEN HIGHER.
Cypress is the only company to deliver on-chip 10-V Tx
and our proprietary Tx-Boost™ multi-phase Tx drives
SNR to unmatched heights. The flagship TMA5XX
product family builds on this with two unique tools. First,
a new touchscreen subsystem architecture combines
narrow-band response with high-frequency sampling
and advanced hardware DSP filtering. Next, an
increased ADC channel count allows TMA5XX to scan
all Rx lines simultaneously for robust correlated noise
immunity. With this array of tools, Cypress delivers
unparalleled performance in the presence of noise.
As touchscreen-enabled devices
become ubiquitous, it is important to
make touchscreens more affordable
to manufacture and to purchase.
Cypress is here to help designers
with an unmatched portfolio of
single-layer touchscreen solutions
to bring multitouch to the masses.
From our Single-Layer Independent
Multitouch (SLIM) sensor for
unbelievably thin designs, with
full multitouch functionality, to our
patented Backgammon single-layer
sensor (US Patent No. 8,121,283)
for lower-cost touchscreen systems,
there is a Cypress solution for every
application.
Eliminating the second sensor layer
can save manufacturers 40 percent
on sensor costs. It also allows
the creation of a new wave of
exceptionally thin devices.

DualSense™ self- plus mutual-capacitance sensing (US Patent Nos. 8,358,142; 8,319,505; and 8,067,948)
