JMicron/JMB350
JMB350
SATA II Port Multiplier (1 to 2 ports)
Description
The JMB350 is a bridge controller, which translates the communication protocol between SATA II 3.0G. This
chip integrated 83MIPS 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 JMB350 to the following applications.
¾ eSATA to dual SATA bridge port multiplier application
¾ One-button system backup application for above applications. (With SATA Vender Software Application)
