Cypress’s New TrueTouch® Gen5 Touchscreen Controller Delivers Industry-Best
Noise Rejection to Large-Screen Superphones and Tablets
TMA568 Controller Supports Precise Passive Stylus Functionality and Palm
Rejection While Silencing Noise from Chargers and Displays
SAN JOSE, Calif. -- October 7, 2013
Cypress Semiconductor Corp. (NASDAQ: CY) today introduced a new controller in
its TrueTouch^® Gen5 family that brings the world’s best noise-immunity
touchscreen control technology to superphones, smartphones, tablets and
e-readers. The TMA568 controller supports writing and drawing with a
2.0-mm-tip passive stylus, enabling touchscreens to capture characters as
small as 7 mm. This capability is important for writing in languages that
require enhanced character recognition for reliable text input, such as
Chinese and Japanese. The controller also adds a palm rejection feature to the
Gen5 family that recognizes a user’s palm touching the screen and prevents
unintended touch inputs.
Electronic noise from displays and after-market chargers can disrupt a
touchscreen’s ability to operate properly. The TrueTouch Gen5 family’s
ChargerArmor™ feature delivers unprecedented 40 volt peak-to-peak (Vpp)
charger noise immunity measured from 1 to 500 kHz with an ultra-thin 0.5-mm
cover lens and a finger-size up to 22 mm—the most stringent specifications
used to measure any touchscreen controller. No competing controllers deliver
noise immunity over 15 Vpp under these conditions. Along with leading noise
performance, the new TMA568 controller delivers superior responsiveness by
integrating 58 sense I/Os and 21 parallel receive channels, enabling scanning
of the entire panel in a single pass. The controller provides precise tracking
of smaller fingers and styluses by allowing for tight spacing of touchscreen
sensors, and it supports screens up to 8.3 inches at a 5.0-mm sensor pitch.
More information on the new TMA568 controller and an introductory video are
available online at touch.cypress.com.
“We specifically designed our new TMA568 controller to deliver the features
and performance required for next-generation superphones and tablets,” said
John Carey, Senior Director of TrueTouch Marketing at Cypress. “In addition to
providing the Gen5 family’s leading charger noise immunity and waterproofing,
TMA568 brings precise stylus support, palm rejection and responsiveness to
larger size touchscreens.”
With Cypress’s unique and patented DualSense™ technology to execute both
self-capacitance and mutual-capacitance measurements in the same device, the
Gen5 family offers the industry’s best waterproofing for seamless performance
in real-world conditions, including the presence of rain, condensation, or
sweat. By combining this powerful architecture with an industry leading 32-bit
ARM^® Cortex™ M-Core processor that is known for high-efficiency MIPS/mW, the
TMA568 controller boasts 120-Hz refresh rates, and averages low power
consumption of 12 mW in active mode and 15 uW in deep-sleep mode.
Gen5 controllers drive the touchscreen at 10V and at high frequency with
narrow-band, single-pass scanning and advanced hardware DSP filtering. The
family’s unmatched noise immunity enables designers of next-generation
handsets to implement ultra-thin, display-integrated stackups, including
In-Cell, On-Cell, & direct lamination onto a noisy display. The result will be
thinner, sleeker end products with a flawless user experience.

Cypress’s touch-sensing portfolio is the industry’s broadest and most
well-adopted, encompassing TrueTouch, CapSense^®, and TrackPad solutions. The
company’s IP portfolio is unmatched, including true single-layer sensor
solutions for dramatically reduced touchscreen costs and self and mutual
capacitance sensing on the same chip that enables advanced features such as
waterproofing, proximity sensing, support for 2-mm stylus, and hover.
Cypress’s TrueTouch technology provides the industry’s best noise immunity,
highest SNR, fastest refresh rates, lowest power consumption, and world’s best
accuracy and linearity. The flexible TrueTouch solution allows customers to
rapidly develop leading-edge solutions without having to buy turnkey modules.
They have a choice of using touch sensors (glass or film) and LCDs from
preferred partners, and can develop innovative mechanical designs ranging from
flat to curved surfaces of varying thickness. In addition, TrueTouch devices
offer Cypress’s legendary noise immunity with patented capacitive sensing
technology that enables flawless operation in noisy RF and LCD environments.
