MPC8241LVR266D NXP MPU

MPC8241LVR266D Overview

The MPC8241 Integrated Host Processor fits applications where cost, space, power consumption and performance are critical requirements. This device provides a high level of integration, reducing chip count from five discrete chips to one, thereby significantly reducing system component cost. High integration results in a simplified board design, less power consumption and a faster-time-to-market solution. This cost-effective, general purpose integrated processor targets systems using PCI interfaces in networking infrastructure, telecommunications, and other embedded markets. It can be used for control processing in applications such as routers, switches, network storage applications and image display systems.
