SMSC LAN9512 USER MANUAL Revision 1.0 (12-04-12) LAN9512 Evaluation Board User Manual 1 Introduction The LAN9512 is a high performance, Hi-Speed USB 2.0 hub with a 10/100 Ethernet controller. The LAN9512 contains an integrated USB 2.0 hub, two integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet PHY, a 10/100 Ethernet controller, a TAP controller, and an EEPROM controller. The EVB9512 is an Evaluation Board (EVB) that utilizes the LAN9512 to provide a two port USB 2.0 hub with an integrated 10/100 Ethernet controller. The EVB9512 provides USB connectivity via one type B upstream USB connector and two type A downstream USB connectors. An RJ-45 integrated magnetics Ethernet jack with link/activity LEDs provides 10/100 Ethernet connectivity. The EVB9512 supports both bus-powered and self-powered modes of operation. The EVB9512 includes a 512x8 Microwire EEPROM that may be used to automatically load USB descriptors, USB device configuration, and the MAC address upon reset. A GPIO header provides access to the LAN9512’s general purpose I/O signals. For debugging purposes, the internal LAN9512 TAP controller is accessible via the included JTAG header. A simplified block diagram of the EVB9512 can be seen in Figure 1.1.

These defaults are the recommended configurations for evaluation of the LAN9512. These settings may be changed as needed, however, any deviation from the default settings should be approached with care and knowledge of the schematics and datasheet. An incorrect jumper setting may disable the board. Note: A dashed line in the Settings column of Table 2.1 indicates the board’s default jumper setting.

SMSC LAN9512 USER MANUAL 5 Revision 1.0 (12-04-12) LAN9512 Evaluation Board User Manual 2.5.1 Bus-Powered Operation For bus-powered operation, the EVB9512 must be configured as follows: 2.5.2  JP1 must be in the 1-2 position  JP22 must be in the 1-2 position  The S1 power switch must be in the open position  The +5V power brick must be disconnected from the P1 barrel plug Self-Powered Operation For self-powered operation, the EVB9512 must be configured as follows:  JP1 must be in the 2-3 position (5V select)  JP22 must be in the 2-3 position  The S1 power switch must be in the closed position  The +5V power brick must be connected to the P1 barrel plug Note: The EVB9512 includes a 2A fuse (F1) to protect from overcurrent conditions during selfpowered operation. If this fuse becomes damaged, it can be replaced with a 2A Littlefuse154002. Note: Self-powered operation is the default EVB9512 configuration. 2.6 Mechanicals Figure 2.2 details the EVB9512 mechanical dimensions and properties.
