JMB352
High-Speed USB & SATA II Combo to Dual SATA II RAID Bridge
Description
The JMB352 is a bridge controller, which translates the communication protocol between SATA II 3.0G and
Hi-Speed USB commands. The integrated 60MIPS 8051, 3-port SATA II 3.0G and Hi-Speed USB technology
enable users to perform Hi-Speed USB to dual SATA II 3.0G, and eSATA II 3.0G to dual SATA II 3.0G applications
in a signal chip.
In this chip, the Hi-Speed USB controller supports the USB Mass Storage Class Bulk-Only Transport
Specification, and support 3 LUN applications. The SATA controller could be configured as host or device. The
3-port SATA II 3.0G controllers further supports the eSATA to dual SATA communication. Integrated these two
technologies, the user could perform JMB352 to the following applications.
¾ eSATA & Hi-Speed USB combo to dual SATA bridge application with RAID0 or RAID1 or JBOD function.
(USB Default Driver of OS)
¾ Hi-Speed USB to SATA with 3 LUN bridge application (USB Default Driver of OS)
¾ Dual eSATA & Hi-Speed USB to SATA application (USB Default Driver of OS)
¾ One-button system backup application for above 3 applications. (With SATA, USB Vender Software
