USB flash disk features MP3 functionality

Trumpion and Micronas GmbH have announced the availability of the UstickMP3 reference design that is a removable USB flash disk. Featuring Trumpion's t3552 USB-to-SmartMedia/MemoryStick controller alongside Micronas' MAS 3507D audio decoder, the eUstickMP3 reference design is described as a cost-competitive total solution aiming at upgrading entry-level removable USB 1.1 flash disks by integrating basic MP3 functions.

In MP3 player mode, the product supports the basic functions of an MP3 player, operated through a user interface for keying inputs. Control functions include power on/off, play, pause, next/previous song, volume, and repeat.

Maintaining the same software interface as Trumpion's eUstick equipped with the t3551, the eUstickMP3 supports the removable disk driver for Windows 98/98SE and driver-less for Windows 2000, ME and XP. It also works with the Mac OS and Linux OS.

The eUstickMP3 reference design is available with demo boards and information package of bundled software, driver, manufacturing tool, reference schematics, PCB layout files, specification, and other documentations.
