MPC8349E

PowerQUICC II™ Pro

Overview

Freescale Semiconductor’s MPC8349E

PowerQUICC II™ Pro family of integrated

communications processors is a next-generation

extension of the popular PowerQUICC II line.

Based on a system-on-chip (SoC) architecture,

the MPC8349E PowerQUICC II Pro Family

integrates the enhanced e300 core, built on

Power Architecture™ technology, and advanced

features, such as DDR/DDR2 memory, Dual

Gigabit Ethernet, Dual PCI and Hi-Speed

USB controllers. With clock speeds scaling to

667 MHz, the MPC8349E family of processors

offers the highest performing PowerQUICC II

devices available.

The MPC8349E PowerQUICC II Pro Family

is designed to provide a cost-effective, highly

integrated control processing solution that

addresses the emerging needs of networking,

communications and pervasive computing

applications. MPC8349E processors can be

used in applications such as Ethernet routers

and switches, wireless LAN (WLAN) equipment,

network storage, home network appliances,

industrial control equipment, copiers, printers

and other imaging systems.

e300 SoC Platform

The MPC8349E PowerQUICC II Pro Family

is based on the e300 SoC platform—making it

easy and fast to add or remove functional

blocks and develop additional SoC-based

family members targeting emerging market

requirements. The e300 core, built on Power

Architecture technology, is an enhanced version

of the 603e core used in previous generations.

Enhancements include twice as much L1 cache

features. The e300 core is completely

software-compatible with existing 603e

core-based products.

Integrated Security

The MPC8349E Family features a powerful

integrated security engine derived from

Freescale’s security coprocessor product

line. The MPC8349E Family’s security

engine supports DES, 3DES, MD-5, SHA-1,

AES and ARC-4 encryption algorithms, as

well as a public key accelerator and an

on-chip random number generator. The

security engine is capable of single-pass

encryption and authentication, as required

by IPsec, IEEE® 802.11i standard and other

security protocols.
