product brief
Overview
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.
• eSATA to dual SATA bridge port multiplier application
• One-button system backup application for above applications. (With SATA Vender Software Application)
