Description
The JM20337 is a single chip solution that bridges between USB 2.0, SATA, and ATA/ATAPI-based mass storage devices. It supports the translation of USB 2.0 mass storage commands to serial ATA and ATA/ATAPI communication protocols. This chip adheres to the Mass Storage Class Bulk-Only Transport Specification and supports dual LUN operation, allowing it to connect to two ATA/ATAPI devices or one ATA/ATAPI device associated with one SATA device. With an embedded command parser, it supports both ATA and ATAPI command sets with LBA48 bit addressing capability.
