Cypress EZ-Color™ Solution Adds ColorLock™ Optical Feedback Support To Help LED Designers Maintain Perfect Color

Solution also Adds More Tools to Support White Lighting, Bringing Code-Free Design to a Broader Range of Applications

SAN JOSE Calif., April 2008 - Cypress Semiconductor Corp. (NYSE: CY) today announced significant enhancements for its award winning EZ-Color™ design solution for intelligent color and white LED lighting systems. The new ColorLock™ feature enables designers to use optical feedback to automatically ensure precise color points over time and temperature for applications such as LCD backlighting, architectural lighting and more. The EZ-Color solution also adds new tools to further support white lighting design. Both features dramatically cut design time by allowing users to complete designs without any C or Assembly coding required.

The EZ-Color family of LED controllers combines with PSoC Express™, the industry’s first visual embedded design tool to deliver a complete design solution for growing applications such as general illumination, architectural lighting, general signage, entertainment lighting and more. The solution enables designers to simply select an LED part number, choose either temperature or optical feedback, and choose a color, including white.

“The new ColorLock optical feedback feature and further white lighting support bring the EZ-Color benefits of simplified design and faster time-to-market to a much broader range of applications,” said Gopal Garg, managing director of the Lighting Solutions Business Unit for Cypress.

For LCD backlight and other applications that need optical feedback, the new ColorLock feature provides an easy way for designers to guard against LED degradation caused by heat and time" Users can calibrate a color sensor and set the color coordinates using either industry standard 1976 CIELUV or 1931 XYZ color space charts, and then set a range of allowable deviations. Adding to the precision of intelligent lighting, Cypress has incorporated the ability to alter a single LED or set color point for streamlined calibration. The EZ-Color controller receives input from the color sensor and, working in concert with PSoC Express, automatically adjusts the flux output of the LEDs to match the color specified by the designer.

The upgraded EZ-Color solution has also simplified the optimization of the Color Rendering Index (CRI) of white lighting designs by giving users the ability to select white light temperatures points that reproduce the widest range of colors. CRI is a measure of how well a light source can reproduce the natural colors of objects.

Cypress also introduced the new CY3263 evaluation kit, which provides the firmware to create ColorLock drivers in PSoC Express, along with a color sensor and control loop targeted at the LCD backlight, architectural lighting and general signage markets. The evaluation board has a dedicated test pin for the DMX512 protocol, which is ideal for creating intelligent lighting networks. The kit includes a MiniProg, a 5v LCD display, a USB cable, a CD with PSoC Express, Gerber files and schematics. The kit is available on the Cypress Online Store at www.cypress.com and from authorized distributors for US$249.
