No. An EEPROM is not required due to the LAN9500/LAN9500i’s ability to be configured using
straps and in-band USB vendor commands. However, use of an EEPROM is suggested. The
EEPROM contains important register setup information, including the Ethernet MAC address
and the USB VID/PID. The USB VID/PID is only programmable through the EEPROM.
A USB Vendor ID may be obtained from the USB-Implementer Forum:

An Ethernet MAC address block can be obtained from the IEEE Standards Association:
