JM20338Plus
Hi-Speed USB ,SATA & PATA Combo Bridge
Description
The JM20338Plus is a bridge controller, which translates the communication protocol between
SATA, Hi-Speed USB and PATA (ATA/ATAPI) commands. The embedded SATA and USB Phys
technology enable users to perform Hi-Speed USB to PATA, Hi-Speed USB to SATA, and SATA to
PATA applications in a signal chip. In this chip, the SATA to PATA and PATA to SATA controllers are
inherited from JMicron’s JM20330, which provides the capability to handle both ATA and ATAPI
PACKET commands. The JM20338Plus could apply to the following applications, (1) Hi-Speed USB
to dual PATA devices, (2) Hi-Speed USB to PATA + SATA combo, (3) Hi-Speed USB to SATA device,
and (4) SATA and Hi-Speed USB combo to PATA device.
