This document provides an overview of the MPC8315E

PowerQUICC™ II Pro processor features, including a block

diagram showing the major functional components. The

MPC8315E contains a core built on Power Architecture™

technology. It is a cost-effective, low-power, highly

integrated host processor that addresses the requirements of

several storage, consumer, and industrial applications,

including main CPUs and I/O processors in network attached

storage (NAS), voice over IP (VoIP) router/gateway,

intelligent wireless LAN (WLAN), set top boxes, industrial

controllers, and wireless access points. The MPC8315E

extends the PowerQUICC II Pro family, adding higher CPU

performance, new functionality, and faster interfaces while

addressing the requirements related to time-to-market, price,

power consumption, and package size. Note that while the

MPC8315E supports a security engine, the MPC8315 does not.
