New Cypress TrueTouch™ Controllers Provide Industry-Leading 1-mm Resistive Stylus Replacement Support For Capacitive Touchscreens

Last Updated: January 05, 2011

Unique Feature Allows Manufacturers to Replace Resistive Touchscreens with More Attractive and Durable Capacitive Technology

SAN JOSE, Calif., January 6, 2011 – Cypress Semiconductor Corp. (NASDAQ: CY) today announced two new families of its leading TrueTouch™ touchscreen controllers that are targeted at stylus-enabled capacitive touchscreen devices. The CY8CTMA340-XXX-03 and CY8CTMA340-XXX-11 families deliver the industry’s only solution for thin (as small as 1 mm) stylus use on capacitive touchscreens.

The traditional benefit of resistive touchscreens until now has been superior stylus support. Many Asian languages require enhanced character recognition for reliable text input, and therefore resistive technology continues to be used despite its poor durability and display quality. Cypress’s new TrueTouch controllers deliver a true “Resistive Stylus Replacement” (RSR) solution that matches the size and performance of resistive stylus implementations while providing the additional benefits of the capacitive touch solution.  No other touch suppliers are currently able to provide this functionality, which enables lower cost feature phones as well as smart phones in Asia to shift to superior capacitive touchscreens from resistive technology.

“Cypress is unique in our ability to dynamically switch between self-capacitive and mutual-capacitive sensing methods,” said Dhwani Vyas, vice president of the User Interface Business Unit at Cypress. “This advantage allows us to be the only touchscreen controller supplier that can deliver Resistive Stylus Replacement, and positions us to introduce new, unique features going forward that our customers can use to differentiate their end products, especially for the Asian market. The touchscreen revolution is just getting started, and Cypress technology such as RSR will help to drive it forward.”

The new families provides all the traditional benefits of Cypress’s TrueTouch technology, including very high signal-to-noise ratio of more than 80:1 RMS, low power consumption (less that 1.3 mA low-power state current), best-in-class water rejection and wet-finger tracking, and more. In addition, they provide highly accurate stylus tracking accuracy better than 0.7 mm, along with 120Hz refresh rates for full handwriting recognition.

The CY8CTMA340-XXX-03 (two-finger support) and CY8CTMA340-XXX-11 (four-finger support) device families are both available today from Cypress. Qualified customers can contact Cypress for more information and to obtain samples.

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.

The next-generation high performance TMA300 multi-touch all-point family provides best-in-class scan times for true multifinger touch and superior signal-to-noise ratio for the most demanding touchscreen applications. Additional information about the TrueTouch solution is available at
