Freescale Semiconductor


Connect Serial to Ethernet in Seconds



Overview

MCF51CN Ethernet MCUs are low-cost, low-power, high-performance 32-bit devices designed for developers who want to add Ethernet connectivity to their commercial and industrial applications. Backed by Freescale’s extensive development ecosystem, the highly integrated MCF51CN devices combine a 10/100 Base-T/TX Fast Ethernet controller (FEC) and media independent interface (MII) to give developers an easy way to connect an external physical layer (PHY) transceiver. This device also includes a multi-function external bus and multiple communication interfaces for various Ethernet gateway applications.
