JMicron JM20338+
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. 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.| Part No. | JM20338+ |
