Cypress lancerer nye TrueTouch controllere

Ny unik feature gør det muligt at erstatte resistive touchscreens med mere attraktive og robuste løsninger baseret på kapacitiv teknologi (in english)

Cypress Semiconductor has 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. 

- Cypress is unique in our ability to dynamically switch between self-capacitive and mutual-capacitive sensing methods, says 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.
