Chapter 19
Fast Ethernet Controller (FEC)
19.1
This chapter provides a feature-set overview, a functional block diagram, and transceiver
connection information for both the 10 and 100 Mbps MII (Media Independent Interface), as well
as the 7-wire serial interface. Additionally, detailed descriptions of operation and the programming
model are included.
19.1.1 Overview
The Ethernet Media Access Controller (MAC) is designed to support both 10 and 100 Mbps
Ethernet/IEEE 802.3 networks. An external transceiver interface and transceiver function are
required to complete the interface to the media. The FEC supports three different standard
MAC-PHY (physical) interfaces for connection to an external Ethernet transceiver. The FEC
supports the 10/100 Mbps MII and the 10 Mbps-only 7-wire interface, which uses a subset of the
MII pins.
19.1.2 Block Diagram
The block diagram of the FEC is shown below. The FEC is implemented with a combination of
hardware and microcode. The off-chip (Ethernet) interfaces are compliant with industry and IEEE
802.3 standards.

Introduction
Please note that the MCF5232 and MCF5233 do NOT contain an FEC
module. Please refer to
The GPIO module must be configured to enable the peripheral
function of the appropriate pins (refer to
Purpose I/O
Module”) prior to configuring the FEC.
