Cypress Semiconductor Corp. (NASDAQ: CY) today announced the US Patent
Office has issued Cypress its one hundredth patent related to its TrueTouch®
capacitive touchscreen controllers. The patent, numbered 8,610,443,
relates to attenuator circuits that contribute to the TrueTouch Gen5
family’s unmatched immunity to electrical noise from chargers and
displays, which can render touchscreens for smartphones, superphones,
tablets, e-readers and other portable devices unusable. Cypress is
continuing to expand its intellectual property (IP) portfolio at the
industry’s highest rate with more than 200 patents pending, protecting
the competitive advantage of its TrueTouch offerings and their
differentiating features.
In addition to patents related to noise immunity, Cypress’s patented
DualSense™ technology allows TrueTouch solutions to execute both
self-capacitance and mutual-capacitance measurements in the same device.
This enables the Gen5 family to offer the industry’s best waterproofing
for seamless performance in real-world conditions, including the
presence of rain, condensation or sweat. Cypress also holds patents
related to panel construction, mutual capacitance sensing, scanning
methods, setting baselines, and tracking and identification of fingers,
styluses and other objects.
Cypress is demonstrating its TrueTouch portfolio in customer meetings at
the Consumer Electronics Show in Las Vegas, Nevada from January 7-10,
2014.
“Earning our one hundredth capacitive touch related patent demonstrates
both the strength of our touchscreen IP portfolio and the true
technological innovation behind the unique features and leading
performance of our TrueTouch solutions,” said John Carey, Senior
Director of TrueTouch Marketing at Cypress. “With more than 200 more
patents currently pending, Cypress is committed to continuing
development of differentiating features that enable our customers to
create the market’s next-generation products.”
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 10 Vpp
under these conditions. And with a more common finger size of 9 mm, Gen5
controllers deliver 60 Vpp. Another patented element of TrueTouch’s
noise resistance is its unique ability to deliver on-chip 10V Tx and
Tx-Boost™, a multi-phase Tx solution to increase signal strength as
needed, providing an unmatched signal-to-noise ratio.
Gen5 controllers drive the touchscreen at 10V and at high frequency with
narrow-band, single-pass scanning and advanced hardware DSP filtering.
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 family boasts 120-Hz refresh rates, and
averages low power consumption of 12 mW in active mode and 15 uW in
deep-sleep mode. The family’s unmatched noise immunity enables designers
of next-generation handsets to implement ultra-thin, display-integrated
stackups, including In-Cell, On-Cell, and direct lamination onto a noisy
display. The result will be thinner, sleeker end-products with a
flawless user experience.
Touch Leadership
Cypress’s touch sensing portfolio is the industry’s broadest and best
