Data Sheet: Technical Data
This document provides an overview of the MPC8314E
PowerQUICC™ II Pro processor features, including a block
diagram showing the major functional components. The
MPC8314E 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 MPC8314E
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
MPC8314E supports a security engine, the MPC8314 does
not.
