Integrated Communications Processors

MPC8309 PowerQUICC II Pro Processor

Overview

The MPC8309 processor is part of the entry

level MPC830x communications portfolio based

on the e300 core architecture. It addresses

the requirements of networking applications,

including I/O cards for low-end base stations,

low-end Ethernet switches, residential

gateways, modem/routers, industrial control,

factory automation and test and measurement

applications. The MPC830x portfolio extends

current PowerQUICC processor offerings,

delivering an impressive 1.99 DMIPS/MHz

in CPU performance, additional functionality

and faster interfaces while maintaining

code compatibility with PowerQUICC I

and PowerQUICC II processors. MPC830x

processors also provide sub-$10, low power

consumption, a compact board footprint and a

time to market advantage through cost-effective

evaluation kits with optimized BSP and drivers.

Core Complex

The MPC8309 incorporates the e300c3

(MPC603e-based) core, built on Power

Architecture® technology, which includes 16 KB

of L1 instruction and data caches, dual integer

units and on-chip memory management units

(MMUs).

QUICC Engine Technology

A communications complex based on

QUICC Engine technology forms the heart

of the networking capability of the MPC830x

portfolio. The QUICC Engine block contains

several peripheral controllers and a 32-bit

RISC controller. Protocol support is provided

by the main workhorses of the device—the

unified communication controllers (UCCs).

Each of the five UCCs can support a variety

of communication protocols, including 10/100

Mbps Ethernet and high-level data link control

(HDLC). Two of the UCCs can also support

IEEE® 1588 version-2 time stamping.

System Interface Unit

The MPC8309 processor also includes a 16/32-

bit double data rate (DDR2) memory controller

with ECC support, 4 x CAN, 4 x UARTs,

High-Speed USB 2.0 controller, enhanced

SDHC controller, a 32-bit peripheral

component interconnect (PCI) controller,

a 16-bit local bus and two direct memory

access controllers (DMAC).

In summary, the MPC8309 provides users

with a highly integrated, fully programmable

communications processor helping to ensure

that a cost-effective system solution can be

quickly developed while offering the flexibility

to accommodate new standards and evolving

system requirements.
