| JMicron/JM20336 JM20336 Hi-Speed USB & SATA II 3.0G Combo to SATA II 3.0G Bridge Description The JM20336 is a bridge controller, which translates the communication protocol between SATA II 3.0G www..com and Hi-Speed USB commands. The integrated 15MIPS 8051, dual-port SATA II 3.0G and Hi-Speed USB technology enable users to perform Hi-Speed USB to SATA II 3.0G, and SATA II 3.0G to 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 dual LUN applications. The SATA controller could be configured as host or device. The dual-port SATA II 3.0G controllers further support the SATA to SATA communication.
