The Ethernet peripheral enables the STM32F4xx to transmit and receive data over Ethernet
in compliance with the IEEE 802.3-2002 standard.
The Ethernet provides a configurable, flexible peripheral to meet the needs of various
applications and customers. It supports two industry standard interfaces to the external
physical layer (PHY): the default media independent interface (MII) defined in the IEEE
802.3 specifications and the reduced media independent interface (RMII). It can be used in
number of applications such as switches, network interface cards, etc.
The Ethernet is compliant with the following standards:
•
IEEE 802.3-2002 for Ethernet MAC
•
IEEE 1588-2008 standard for precision networked clock synchronization
•
AMBA 2.0 for AHB Master/Slave ports
•
RMII specification from RMII consortium
