圖1.MCF5441x方框圖 TWR-MCF5441X-KIT評估模塊 The TWR-MCF5441X-KIT module is part of the Freescale Tower System, a modular development platform that enables rapid prototyping and tool re-use through reconfigureable hardware. The TWR-MCF5441X-KIT features the MCF54418 microprocessor which offers MCU peripherals with MPU performance, including integrated analog, an L2 switch and dual ethernet. Add Linux and MQX RTOS, plus Eclipse-based CodeWarrior IDE and you’ve got a powerful development package for network-connected industrial applications. The TWR-MCF5441X platform provides and evaluation system for the Freescale MCF5441x ColdFire V4m embedded microprocessor family. The MCF54418 is the superset device in the family and is the processor featured on this platform. This allows evaluation and development for the entire MCF5441x family on an existing Tower system. The TWR-MCF5441X provides hardware to evaluate as many of the configurations of the MCF5441x family as possible.
