JMicron/JMB352U JMB352U High-Speed USB & SATA II Combo to Dual SATA II Port Multiplier(1 to 2) Bridge Description The JMB352U is a bridge controller, which translates the communication protocol between SATA II 3.0G. This chip integrated 60MIPS 8051, and provide eSATA II 3.0G to dual SATA II 3.0G port multiplier applications in a single chip. In this chip, 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 JMB352U to the following applications. ¾ eSATA to dual SATA bridge port multiplier application ¾ One-button system backup application for above applications.
