The MCF528x family represents the first microcontrollers based on Freescale Semiconductor´s 32-bit ColdFire core integrated with Ethernet, Flash and CAN. These devices offer advanced communications features, a rich peripheral set and a variety of supporting software and development tools. The MCF528x is designed to simplify embedded Ethernet-networked microcontroller applications. With its integrated 10/100 Mbps Ethernet MAC and network-ready applications software, the MCF528x brings standards-based networking to a variety of traditional MCU applications including food service equipment, security systems, vending machines, exercise equipment and industrial controllers. Applications in all of these areas will benefit from networking functions such as Web-based user interfaces, network time synchronization, and router/gateway functionality for legacy serial protocols.
