SAN JOSE, Calif., 2005年5月3日 - Cypress Semiconductor Corp. (NYSE: CY), the market leader in USB, today announced that Texas Instruments Incorporated (TI) has selected its EZ-USB FX2LP and EZ-OTG USB peripheral/host controllers for inclusion in the TI TMS320DA255 DSP-based reference design for portable digital music players.

TI's reference design is a turnkey, manufacturable reference design for portable hard-disk drive-based music players. It includes a 5-GB HDD, integrated FM tuner, microphone and USB host. Devices using this design can play up to 15 hours of music in MP3, WMA and WAV formats, as well as display JPEG and MPEG-4 photos.

The DA255 reference design relies on two Cypress USB controllers to connect to other devices. Cypress's EZ-USB FX2LP (CY7C68013A) is a flexible, high-speed USB 2.0 controller with the industry's lowest power consumption. USB peripherals using the EZ-USB FX2LP controller-including mass storage devices and personal media players-are able to operate off of the power of the USB bus. EZ-OTG (CY7C67200), based on the USB On-The-Go (OTG) protocol, enables direct connectivity between portable devices, such as cell phones, PDAs, video and still cameras, MP3 players and mass storage peripherals. 

"We needed our DA255 reference design to be low power and high performance, yet cost effective," said Raj Chirayil, marketing manager, Portable Audio and Infotainment business, Texas Instruments. "Cypress's USB products fit our requirements perfectly. They provide us with both the features and the headroom to lead the market today and down the road."

"We are very pleased to have collaborated with TI on this innovative design," said Bassil El-Kadi, product manager in Cypress's Consumer and Computation Division. "Our EZ-USB FX2LP and EZ-OTG products give the design a great deal of flexibility. In addition to downloading music in various formats, users can download photos from their cell phones; save music from the FM tuner to internal storage; or display MPEG movies from their digital still cameras. We believe the combination of features and flexibility that our USB products provide will help power the dramatic growth of the portable media player market."

The EZ-USB FX2LP is a fully integrated peripheral controller, including an 8051 microprocessor, a serial interface engine, a high-speed USB 2.0 transceiver, on-chip RAM and FIFO and a general programmable interface. Its unique architecture handles all basic USB functions, enabling the host system's microprocessor to focus on application-specific functions and ensuring sustained high-performance data transfer rates. Featuring a data rate of 480 Mbps, 16 Kbytes of on-chip memory, and up to 40 programmable I/Os, Cypress's EZ-USB FX2LP solution provides world-class design flexibility. There are also several package options, including a space-saving 8mm x 8mm QFN package, ideal for use in small form-factor mobile applications. The CY3684 EZ-USB FX2LP Development Kit is available to facilitate the design process and speed time-to-market for customers. CY4611B EZ-USB FX2LP Reference Design Kit to facilitate flexible mass-storage designs will be available in Q2'05.

About EZ-OTG
EZ-OTG (CY7C67200) contains most of the functionality of EZ-Host but is customized for mobile devices-including cell phones, PDAs, video and still cameras, MP3 players and mass storage devices. Supporting the USB On-the-Go (OTG) protocol, EZ-OTG enables true "plug-and-play" connectivity between portable devices. EZ-OTG contains two USB serial interface engines (SIEs), with one port per SIE, and a power-boost circuit that operates down to 2.7V.

Cypress solutions are at the heart of any system that is built to perform: consumer, computation, data communications, automotive, industrial, and solar power. Leveraging a strong commitment to customer service and performance-based process and manufacturing expertise, Cypress's product portfolio includes a broad selection of wired and wireless USB devices, CMOS image sensors, timing solutions, network search engines, specialty memories, high-bandwidth synchronous and micropower memory products, optical solutions, and reconfigurable mixed-signal arrays.
