Cypress Enables High-Performance Capacitive Touchscreens to Replace Resistive With New TrueTouch™ Solution for Single-Layer...

Business Wire
Cypress Semiconductor Corp. (NASDAQ:CY) today unveiled a
breakthrough feature for its TrueTouch™ touchscreen controllers
that enables manufacturers of handsets, cameras, GPS systems and
other mobile systems to offer the benefits of capacitive
touchscreens at resistive touchscreen costs. The new feature
available for Cypress’s CY8CTST241 (single-touch with one-finger
gestures) and CY8CTST242 (adds limited two-finger gestures such as
“pinch” and “zoom”) delivers high performance touchscreen accuracy
and responsiveness with a true single-layer sensor panel,
drastically reducing the cost of the most expensive component of
the touchscreen.
Increasingly, capacitive touchscreens are viewed as a
differentiator by buyers of new mobile devices. Capacitive
advantages over resistive touchscreens include a more intuitive
user experience, better transmissivity, lower power, increased
reliability and better durability. Many lower-priced “feature
phones” do not offer capacitive touchscreens today because of the
cost. The new TrueTouch single-layer sensor opens up new “feature
phones” and lower-cost smartphones to capacitive touchscreens,
especially in major markets such as China and India.
Traditional capacitive touchscreens use a two-layer sensor to
deliver the accuracy and linearity required for today’s user
experience. Cypress has developed proprietary algorithms that
interface with a true single-layer sensor with no bridges to
deliver two-layer performance for an unparalleled combination of
user experience and cost sensitivity. The removal of this second
sensor layer can save mobile device manufacturers 30 percent or
more on sensor costs, and is available today for glass and film.
Even with only one sensor layer, the TrueTouch solution delivers
accuracy better than 1.25 mm, excellent signal-to-noise ratios,
fast response times (80Hz), and best-in-class active power of
3.6mW.
“This is a significant advancement in that it opens up a very
large part of the market to capacitive touchscreens,” said Dhwani
Vyas, vice president of the User Interface Business Unit at
Cypress. “All manufacturers realize the attractiveness of
touchscreens, and Cypress is delivering the performance, durability
and attractiveness of capacitive touchscreens at a significantly
lower price. In fact, leading manufacturers are already beginning
high-volume production with this solution.”

About TrueTouch
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.
Cypress’s CY8CTMA884 is the industry’s first single-chip tablet
solution for touchscreens up to 11.6 inches. The high performance
TMA300 multi-touch all-point family for smaller screens provides
best-in-class scan times for true multi-finger touch and very high
signal-to-noise ratio of more than 80:1 RMS. It also offers low
power consumption (less than 1.3 mA low-power state current),
best-in-class water rejection and wet-finger tracking, and more.
