2. Overview
XRS10L620 is a 2ch-SATA 1ch-IDE controller with PCI-X interface. It can connect up to 4
devices at the same time, 2 SATA devices and 2 IDE/ATAPI devices. With its 32-bit PCI-X
interface, it can easily with any MCU or CPU with PCI/PCI-X interface to form a powerful
subsystem connecting high speed SATA storage devices and low cost IDE HD’s and ODD’s
(optical disc drive).
The excellent compatibility of XRS10L620 with IDE HD’s and ODD’s make it especially
suitable to construct an enclosure device with both IDE HD’s and CD-ROM/DVD-ROM or
CD/DVD burners, such as external SATA/IDE raid box or CD/DVD copy machine.
The two SATA channels on the chip can function in HOST mode. They comply with SATA
Gen1 specification (Gen1 supports 1.5Gbps data rate) and Gen2 (3Gbps data rate) specification. As
for the IDE channel, the maximum transfer rate range from 16.7 MB/s to 150 MB/s. Further more,
data transfer can take place among 3 devices to PCIX bus simultaneously.
