Microchip Technology USB2005-MV-01

Overview

USB2005-MV-01 from SMSC is a USB 2.0 Mass Storage Class peripheral controller integrating an 8051 CPU core, USB 2.0 PHY/SIE, ATA-66 interface, and PD-DRM support for Windows Media Systems. It operates with 2.5 V core and 3.3 V I/O, supports UDMA Mode 4 transfers up to 2048 GB ATA drives, and delivers true 480 Mbps USB 2.0 compliance in a 100-pin STQFP package. It enables portable media player designs requiring removable-media reporting and SCSI Inquiry–based serial number delivery.

For engineers reviewing the USB2005-MV-01 datasheet, USB2005-MV-01 pinout, USB2005-MV-01 application, or USB2005-MV-01 equivalent, key selection criteria include PD-DRM firmware compliance, dual-voltage (2.5 V/3.3 V) power architecture, integrated 48 KB ROM + 768 B SRAM, ATA-66 timing support, and GPIO-controlled IDE interface detachment for shared-drive architectures.

Technical Context

The USB2005-MV-01 implements a tightly coupled architecture: a 30 MHz 8051 microcontroller executes firmware from internal 48 KB ROM or optional external Flash, manages SCSI Inquiry responses for PD-DRM, and controls ATA/ATAPI drive handshaking via dedicated IDE control pins (IDE_nIOR, IDE_nIOW, IDE_IRQ, IDE_DRQ). Its USB subsystem includes full-speed (FS+/FS−) and high-speed (USBD+/USBD−) transceivers with internal PLL generating 480 MHz sampling, 30 MHz MCU, and 60 MHz ATA clocks.

Power management is hardware-assisted: GPIO3 detects VBUS for IDE high-impedance forcing; GPIO1 signals USB SUSPEND state; and nRESET latches ROMEN configuration at startup. The device supports electrically detaching the IDE interface under external microprocessor control-critical for media players sharing a single ATA drive between USB host and local playback engine.

USB2005-MV-01 belongs to SMSC's USB Mass Storage Controller product line, designed specifically for portable media players and USB storage peripherals requiring Microsoft PD-DRM compliance, ATA-66 performance, and minimal external components.

FAQ

What is the primary function of USB2005-MV-01 in a portable media player system?

USB2005-MV-01 serves as the USB 2.0 Mass Storage Class peripheral controller that bridges a standard ATA/ATAPI hard drive or optical drive to a USB host. In portable media players, it enables simultaneous local playback and PC file transfer while enforcing Portable Device Digital Rights Management (PD-DRM) via SCSI Inquiry responses. The USB2005-MV-01 handles all USB enumeration, command parsing, ATA timing, and drive serial number reporting required for Windows Media DRM licensing-making it essential for certified PMP designs.

Does USB2005-MV-01 require an external crystal oscillator?

Yes, USB2005-MV-01 requires a 12 MHz crystal connected between XTAL1/CLKIN and XTAL2 pins. The device includes an on-board crystal driver circuit and internal PLL that generates the 480 MHz USB sampling clock, 30 MHz MCU clock, and 60 MHz ATA clock from this reference. Using an external 12 MHz clock source instead of a crystal is possible by driving XTAL1/CLKIN directly, but the crystal configuration is the default and validated method per the datasheet.

How does USB2005-MV-01 support drive sharing between a local microprocessor and USB host?

USB2005-MV-01 supports drive sharing through two dedicated GPIOs: GPIO3 (VBUS detect input) forces the IDE interface into high-impedance state when USB is disconnected or suspended, and GPIO1 (SUSPEND indicator output) signals the local microprocessor when the USB bus enters SUSPEND mode. This allows the external microprocessor to safely take control of the ATA bus without contention. The USB2005-MV-01 datasheet defines precise operational conditions-including VBUS detection and GPIO logic levels-for electrically detaching the IDE interface during media playback.

What power supply configuration is required for USB2005-MV-01?

USB2005-MV-01 requires two regulated supplies: +2.5 V ±10% for core logic (VDD/VDDP) and +3.3 V ±10% for I/O and analog circuits (VDDIO/VDDA). The datasheet explicitly recommends deriving the 2.5 V core from the 3.3 V rail using a 1N4001 diode drop-enabling a single 3.3 V regulator design. All I/O pins tolerate 5 V inputs, simplifying level-shifting with legacy peripherals. Total active supply current is 85–120 mA across both rails.

Can USB2005-MV-01 be used with ATAPI devices like CD-ROM or DVD drives?

Yes, USB2005-MV-01 fully supports ATAPI devices including CD-ROM, CD-R, CD-RW, DVD, and DVD±R/W drives. Its ATA/ATAPI interface complies with ATAPI-5 specifications and handles packet command sets required for optical media. The device reports all connected media as removable drives-a requirement for PD-DRM-and supports SCSI Inquiry responses needed for host OS recognition. USB2005-MV-01 has been validated with ATAPI devices in typical application schematics and is explicitly listed in the datasheet's feature set.
