Description
JMicron’s JM20330 is a single chip solution for serial and parallel ATA translation. It includes the Serial ATA PHY, Link, Transport, and Parallel ATA (application layer) controller. The Serial ATA physical, link, and transport layers are compliant to Serial ATA 1.0a. JM20330 supports 1.5GHz data rate. The application layer supports both the ATA register command set and PACKET command set, which could drive both Hard Disk Drive and ATAPI Optical Storage such as CR-ROM, CD-RW, DVD-ROM, DVD-RW, etc. The Serial ATA and the Parallel ATA application layer support both host and device operation and can be configured through a single pin.
