PL-2507 Product Brochure V1.0 08/05/02 1 PL-2507 Hi-Speed USB to IDE Bridge Controller OVERVIEW The PL-2507 is a single chip USB2.0-IDE bridge controller, which is designed to perform a seamless protocol transfer between the USB and ATA interfaces. It will work with full function at full speed or high speed USB transfer mode. The operating speed mode is determined by the capability of the host/hub to which it is connected. The PIO mode 0 to mode 5, Multi Word DMA mode 0 to mode 2, and Ultra DMA mode 0 to mode 4 are implemented to support difference IDE devices. The chip will communicate with the connected device to select the proper mode to obtain the best performance, The chip is implemented according to the USB Bulk-Only Mass Storage Class specification ver 1.0. Since the default driver is supported by most the OS, no additional driver is needed. FEATURES Universal Serial Bus Specification 2.0 Compliant USB Mass Storage Class Bulk-Only Transport Specification Compliant AT Attachment with Packet Interface Extension(ATA/ATAPI) Compliant ATA interface support PIO mode 0 ~ 4, Multiword DMA mode 0 ~ 2, and UltraDMA mode 0 ~ 4 to work with ATA/ATAPI devices Integrate full speed and high speed transceiver 5 V tolerant inputs, 3.3 V output drive Sufficient 4K bytes data buffer for both the downstream and upstream data transfer in optimized performance Support external serial EEPROM to customize vender/product related information Support multiple LUN (optional) Additional General Purpose IO pins for further customization On-chip 3.3v to 2.5v regulator to supply the power of 0.25 process core circuit Inexpensive LQ100 and LQ64 packaging available BLOCK DIAGRAM 3.3V POWER 12MHZ CRYSTAL USB2.0 HOST PLL REGULATOR 3.3/2.5 V USB 2.0 PHY (UTMI) BACKEND SIE LOGIC DEVICE POWER MANAGE MENT INTERRUPT CONTROLLER MEMORY MANAGEMENT UNIT (MMU) UNIFIED RAM 4KB TURBO 8032 CONTROLLER IDE CONTROLLER GPIO 16KB ROM HDD,CD-ROM,CD-RW,DVD,DVD+RW,MO Prolific Technology Inc. 7F, #48, Sec.3, Nan-Kang Rd., Taipei, Taiwan 115, ROC Tel: 886-2-2654-6363 Fax: 886-2-2654-6161 E-mail : sales@prolific.com.tw http://www.prolific.com.tw
