MPC885ZP66 数据手册 - NXP（恩智浦）

Overview

●NXP Semiconductors"s PowerQUICC® architecture containing a core built on Power Architecture technology provides an exceptional combination of price, performance and functionality for networking and communications applications. With the introduction of the MPC885 Family, NXP® takes the price/performance benefits, features and functionality of PowerQUICC I communications processors to the next level. The most advanced and feature-rich PowerQUICC I devices available, the MPC885 family of processors are engineered to deliver on-chip security, dual Fast Ethernet (MII and RMII) ports, USB, and bus speeds scaling to 80 MHz for higher system throughput.

●The MPC885 Family includes the MPC870, MPC875, MPC880 and MPC885 processors. These highly integrated PowerQUICC devices are designed to deliver a versatile, single-chip communications processor and peripheral solution that can be used in a variety of controller applications, excelling particularly in communications and networking products. Ideal applications include low-end routers, VPN routers with integrated security features, home networking equipment, cost-effective WLAN access points and xDSL gateway boxes.
