DATASHEET
Datasheet
PRODUCT FEATURES
LAN9512
USB Hub with Integrated
10/100 Ethernet Controller
Highlights
Two downstream ports, one upstream port
— Two integrated downstream USB 2.0 PHYs
— One integrated upstream USB 2.0 PHY
Integrated 10/100 Ethernet MAC with full-duplex
support
Integrated 10/100 Ethernet PHY with HP Auto-MDIX
Implements Reduced Power Operating Modes
Minimized BOM Cost
