This document provides an overview of the MPC8308

PowerQUICC II Pro processor features, including a

block diagram showing the major functional

components. The MPC8308 is a cost-effective,

low-power, highly integrated host processor that

addresses the requirements of networ king applications

such as low-end printing, smart grid home energy

gateway, data concentrators, wireless LAN access

points, wireless femto base stations, and industrial

applications such as industrial control and factory

automation. The MPC8308 extends the

PowerQUICC II Pro family, adding high CPU

performance, additional functionality, and faster

interfaces while addressing the requirements related to

time-to-market, price, power consumption, and package

size.
