V1.0 12/30/10’ OVERVIEW The PL2775 is a low-power single-chip SuperSpeed USB 3.0 to Dual SATA II compliant bridge IC controller specially designed for external USB 3.0 dual-port RAID and non-RAID applications. It supports RAID 0 (striping) and RAID 1 (mirroring) as well as JBOD (Just a Bunch of Disks) and BIG (single logical disk) mode configurations. The PL2775 can perform seamless protocol transfer between the USB Host and dual SATA interface storage devices like Hard Disk Drives, Optical Disk Drives, and Solid-State Drives. SuperSpeed USB has data transfer bandwidth of up to 5Gbps offering 10X performance increase over Hi-Speed USB (480Mbps) while still retaining backward compatibility and interoperability with all USB 2.0 and USB 1.1 devices, hosts, and hubs. The PL2775 also integrates a high performance 8-bit microcontroller which can be used to support versatile system applications such as one button backup, power control, and other USB port features. The PL2775 chip is also implemented according to the USB Bulk-Only Mass Storage Class Specification v1.0.
