Texas Instruments Inc. (TI) has selected Cypress Semiconductor Corp.'s EZ-USB FX2LP and EZ-OTG. The USB peripheral/host controllers from Cypress will be used for inclusion in the TI S320DA255 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.
