Description

The USB2005 is a USB2.0 Mass Storage Class Peripheral Controller intended for use with standard ATA-5 and -6 hard in media player applications requiring Portable Device Digital Rights Management (PD-DRM) as specified by Microsoft for Windows Media systems. This includes reporting all media as removable drives and providing the drive serial number to the PC host via a SCSI Inquiry command.
The USB2005 consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad and 768 of program SRAM, internal 48 KB program ROM, and an ATA-66 compatible interface.
Provisions for optional external Flash Memory up to 64K bytes for program storage is provided. An optional serial EEPROM which can be modified via USB from the host provides unique VID/PID/Serial numbers, as well as optional configuration information.
Internal 768 Bytes of scratchpad SRAM are also provided. The USB2005 can also be used for program storage to implement program upgrade via USB download to external "boot block" Flash program memory, if desired.
