Cypress Semiconductor Corp. Announces a New Reference Design with Software and Hardware Modules Compliance with Microsoft's New Media Transfer Protocol (MTP) and Cypress's EZ-USB FX2LP (High-Speed ​​USB 2.0 Control) The data is transmitted to meet all the requirements of the platform designer. MTP is an underlying transmission technology that provides digital rights management for portable media players (PMPs).

Cypress's reference design (CY4619) uses Ultra Direct Memory Access (UDMA) technology to significantly increase the read and write speed of hard disk drives (HDDs). It includes USB universal driver software with Mass Storage Class (MSC) and MTP support, as well as Cypress's EZ-USB FX2LP (CY7C68015A) controller firmware. The free CY4619 reference design integrates Texas Instruments' TMS320DA255 DSP-based Raga reference design, making it ideal for HDD digital music players.

Matthew Branda, marketing manager for Cypress's USB products division, said: "UDMA has helped us deliver a superior reference design that supports MTP without sacrificing performance. This is unique. Content owners have access to portable media. In response to this, digital compression management requirements are increasing, and Cypress's solutions address critical needs in the growing media player market."

TI's Raga reference design based on the TMS320DA255 DSP is a turnkey reference design for music players with portable hard drives that can be put into production directly. It includes a 5GB HDD, an integrated FM tuner, a loudspeaker, and a USB host. The device is designed to continuously play up to 15 hours of music, supports formats such as MP3, WMA and WAV, as well as JPEG and MPEG-4 format photos.

Bassil El-Kadi, product manager for Cypress's Consumer Electronics and Computing Division, said: "Cypress's MTP driver has an industry-leading EZ-USB FX2LP performance and TI's superior reference design, creating an excellent development environment for designers. To enable a new generation of PMP players to be implemented quickly and easily."
