GL711FW
1. Overview
The GL711FW is a high-performance 1394 to ATA/ATAPI native bridge with an
embedded SBP-2 target solution. It supports a solution for link/transaction layer
controller conforming to the IEEE Std 1394 (IEEE 1394-1995 and IEEE 1394.a) up to
400Mbps transfer rate. Through the SBP-2 port driver, supported by Microsoft
Windows 2000 and Windows 98 SE, Windows ME, SCSI class drivers can use SBP-2
to communicate with IEEE 1394 device using the SCSI command set. By means of the
embedded 8052 processor running the firmware located in ROM (internal or optionally
external) GL711FW provides an SBP-2 protocol engine to automatically achieve the
transport of SCSI command and data over IEEE Std 1394 serial bus. GL711FW
provides a memory interface for reading/writing firmware from/to external Flash ROM,
so that it makes software download easily and helps testing, development, or other
specific application purpose. GL711FW also supports an 8051 interface, which allows
external 8051 to access the internal memory when the embedded 8052 was disabled for
debugging and testing. The GL711FW is ideally suited to hard disk drives (HDDs),
MO, CD-ROM, CD-R, CD-RW and DVD. It allows IDE drives being able to connect
to a 1394 serial bus in a plug-and-play fashion. The ATA/ATAPI interface of
GL711FW supports signal timing up to Ultra-DMA mode 5.
