ASM3042

General Description

ASMedia ASM3042 is the next generation Universal Serial Bus xHCI host controller, bridging PCI Express to USB3.2, compliant with USB3.2 Specification Revision 1.0 and Intel eXtensible Host Controller Interface specification revision 1.1. It also supports backward compatible with legacy USB function and devices, compliant with USB Attach SCSI Protocol revision 1.0, supporting the function of debug port on port A of USB.

ASM3042 supports two ports of USB3.2 Gen1 x1 and performs exceptional high speed bandwidth with the support of PCI Express Gen3. It uses advance process with low voltage supply, following standard PCI Express/USB bus power management and advance chip power management to reduce total power consumption efficiently under idle/standby state.
