USB2005-MV-01

Specialized Overview

The USB2005-MV-01 is a USB 2.0 Mass Storage Class Peripheral Controller designed for ATA/ATAPI devices, featuring Portable Device Digital Rights Management (PD-DRM) support compliant with Microsoft Windows Media Systems specifications. It integrates a USB 2.0 PHY and SIE, an ATA-66 compatible interface, and a Fast 8051 microprocessor operating at 30 MHz. The device includes 48 KB internal ROM, 768 bytes of program SRAM, and supports up to 64 KB of external code space. It provides double-buffered bulk endpoints with 512-byte buffers and operates on a 2.5V core with 3.3V I/O tolerant to 5V inputs.

Specialized Feature Summary

• Supports PD-DRM via SCSI Inquiry commands for Windows Media systems
• Integrates Fast 8051 microprocessor with expanded scratchpad memory
• Provides true UDMA Mode 4 transfer rates for ATA-6 drives
• Enables electrical detachment of the IDE interface under microprocessor control

Specialized Applications

• Portable media player applications requiring digital rights management
• Interfacing ATA or ATAPI devices to USB 2.0 bus
• USB Mass Storage Compliant Bootable BIOS implementations

Specialized Procurement Notes

Verify component authenticity by checking markings against the SMSC datasheet revision 0.2. Confirm package details match the 100-pin STQFP lead-free RoHS compliant specification. Ensure ordering suffixes align with the required voltage and pinout configurations. Request anomaly sheets if specific operational deviations are anticipated during integration.

Specialized Selection Notes

Select this controller for designs requiring native ATA/ATAPI interfacing with USB 2.0 compliance. Consider the integrated 8051 processor for low-speed control functions and firmware execution. Evaluate the need for external program memory if the 48 KB internal ROM is insufficient. Verify power supply requirements for the 2.5V core and 3.3V I/O domains.

Specialized Part Context

The USB2005 series serves as a bridge between legacy ATA/ATAPI storage interfaces and modern USB 2.0 host controllers. Manufactured by SMSC, now part of Microchip Technology, it addresses the specific needs of portable media players that require strict adherence to digital rights management protocols while maintaining high data throughput capabilities.
