Cypress Semiconductor Corp. (NYSE:CY) is greatly simplifying design of RGB-based white lighting LED systems with Cree XLamp® LEDs. Using Cypress’s PSoC Designer[tm] 5.0 visual design software and the CY3265C-RGB evaluation kit, designers can simply input the selected XLamp device; select bin specifications through easy-to-use drop-down menus; and select white light temperature points as well as specific color points for optimal reproduction of any type of desired light output – without having to write a single line of firmware. Lighting designers no longer need to be experts in LED binning and temperature specifications. Instead they can focus on desired lighting effects, bringing solutions to market more quickly and efficiently.
Cypress’s intelligent lighting solutions simplify white lighting designs by giving users the ability to select white light temperatures points on a gamut in PSoC Designer 5.0 software. Cypress has integrated the XLamp device specifications and temperature characteristics into the content library of PSoC Designer 5.0 software, which supports Cypress’s EZ-Color[tm] LED controllers. With other LED controllers, engineers must input specific device binning and temperature performance data. Cypress has introduced the CY3265C-RGB evaluation kit enabling designers to begin simplified system design with XLamp LEDs.
“We are pleased to support Cree’s XLamp portfolio with our intelligent lighting solutions,” said Curt Davis, vice president of Cypress’s PowerPSoC[tm] Business Unit, which includes Intelligent Lighting Solutions. “Cree has earned a leadership position in bringing LED lighting to the mainstream, and our intelligent lighting solutions can simplify general illumination designs with the XLamp offerings.”
The CY3265C-RGB evaluation kit provides the firmware to support XLamp LEDs. The kit comes with a daughter card featuring XLamp LEDs, and includes a MiniProg, a 5v LCD display, a USB cable, a CD with PSoC Designer 5.0, Gerber files and schematics. The kit is available on the Cypress Online Store at www.cypress.com and from authorized distributors.
About Cypress’s Intelligent Lighting Solutions
LED lighting design requires a complex set of calculations with custom firmware to deliver consistent color. The two biggest problems that LED lighting engineers face are having to account for differing LED performance specifications based on manufacturing bins and the LEDs’ degradation (such as output flux, wavelength etc.) over different temperatures. With PSoC Designer 5.0, designers simply select a color from a gamut presented on-screen. Pre-loaded manufacturers’ bin specifications and choice of either temperature or optical feedback algorithms are automatically applied to the selected design and programmed into an EZ-Color controller. This can save anywhere from weeks to months of design time for a complex design.
EZ-Color LED controllers can support up to 16 LED strings, compared to four or five strings for competitive devices. The additional strings can mean a savings of dozens or even hundreds of controllers in very large designs, cutting design complexity, power consumption and board space. The EZ-Color LED controllers are powered by Cypress patent pending PrISM[tm] (Precise Illumination Signal Modulation) technology. The PrISM modulation technology significantly reduces low-frequency flicker and radiated electro-magnetic interference (EMI) — common problems in LED lighting designs. Designers also have the flexibility to add additional functionality to the EZ-Color controllers, including battery charging, motor control, thermal feedback, programmable control gear and other features.
