JMicron/JM20337 JM20337 Hi-Speed USB to SATA & PATA Combo Bridge


The JM20337 is single chip solution to bridge between USB 2.0, SATA and ATA/ATAPI-based mass storage device. It provides the capability to translate USB 2.0 mass storage commands to serial ATA and ATA/ATAPI communication protocol. The USB adheres to the Mass Storage Class Bulk-Only Transport Specification, and supports dual LUN operation, which could connect to two ATA/ATAPI devices or one ATA/ATAPI device associated with one SATA device. The embedded command parser supports both ATA and ATAPI command set with LBA48 bit addressing capability.
