USB 2.0 to 10/100 Ethernet Controller
Datasheet
Note 2.1
All four SUSPEND states are supported by LAN9500A/LAN9500Ai. SUSPEND3 is not
supported by LAN9500/LAN9500i.
2.1.6
EEPROM Controller
The LAN950x contains an EEPROM controller for connection to an external EEPROM. This allows for
the automatic loading of static configuration data upon power-on reset, pin reset, or software reset.
The EEPROM can be configured to load USB descriptors, USB device configuration, and MAC
address.
Custom operation without EEPROM is also provided (LAN9500A/LAN9500Ai only).
2.1.7
General Purpose I/O
When configured for internal PHY mode, up to eleven GPIOs are supported. All GPIOs can serve as
remote wakeup events when the LAN950x is in a suspended state.
