PRODUC T BRIEF

The PPC405EXr offers the performance of the market

leading PPC405 processor together with a high

performance suite of peripheral and memory interfaces, including PCI

Express, USB2.0 On-the-Go, DDR 2/1 and Gigabit Ethernet. The PPC405EXr also incorporates an advanced

security engine, featuring header/trailer processing capability and support for the broadest range of security

protocols, including IPSec, SSL, and DTLS. The PPC405EXr delivers exceptional performance and is ideally suited

for cost sensitive next generation Residential Gateway and IP-STB applications.

The PowerPC 405 Core

The PowerPC 405 core has been optimized for

system on a chip designs requiring solid

performance, low cost, and low power

consumption. Performance is enhanced through

the use of separate instruction and data cache

units. A 5-stage pipeline further boosts

performance by offering single cycle execution of

most instructions, including loads and stores.

Security

The PPC405EXr integrates the advanced EIP-94

security engine from SafeNet. This security engine

attaches directly to the PLB4 bus for the fastest

possible throughput between the PPC405

processor, memory, and the security engine itself.

The engine supports DES, 3DES, AES, and ARC-4

encryption, MD-5, SHA-1 and SHA-256 hashing. The

packet engine includes a pseudo random number

generator. The header/trailer protocol processor

eliminates any need for security protocol

processing by the PPC405 processor, freeing it to

handle application-based operations, while

improving overall security performance. The

engine incorporates an on-chip true random

number generator and a public key accelerator. The

algorithms are compliant with FIPS-140-2 and ANSI

X9.17 Annex C.

DDR Memory Support

To ensure design flexibility, both DDR1 and DDR2

memory are supported at a maximum data rate of

400Mbps for DDR2.

Ethernet Interface MAC

To ensure that the system level throughput to the

wired infrastructure can keep pace with the much

faster 802.11n data rates, the PowerPC405EXr is

equipped with a single gigabit Ethernet MAC that

is compliant with ANSI/IEEE std. 802.3 and IEEE

802.3u supplement. The gigabit MAC is compliant

with IEEE standard 802.3z. (Gigabit Ethernet), and

supports both half Duplex and Full Duplex

operations, as well as Wake On LAN support. In

addition, it supports 9KB Jumbo frames, GMII, MII,

and RGMII interfaces.

USB2.0 On-the-Go

Able to support either device or host modes, with

data rates of up to 480Mbps.

External Bus Controller (EBC)

EBC operates at up to 100MHz. It provides 8-, 16- or

32-bit data bus, 27-bit address bus, 4 chip selects,

and bus arbitration for ample space and flexibility

for large amounts of RAM, nonvolatile memory, and

external peripherals/ASICs. Both simple and multi-

master configuration systems can be built.

Standard Peripherals

The

chip peripherals. Two UARTs (one with full

hardware modem flow control), watchdog timer,

and a 4-channel DMA controller capable of

transferring data to/from any PLB and OPB slave,

and external bus.

Development Tools Support

PowerPC embedded processors are supported by

AMCC and 100+ third-party vendors through the

PowerPC Embedded Tools program. This program

provides compilers, debuggers, real-time operating

systems, emulators, and a full range of tools to help

manufacturers develop products more quickly. A

PowerPC

help expedite product evaluation and project

development.

PCI Express

To be ready for the next generation of 802.11n

wireless access devices, the 405EXr features a

1-lane PCI Express port. With greater bandwidth,

PCI Express is the preferred choice for high

throughput WLAN access Points, Gateways and IP

Set Top Boxes. The PCI Express port can support 2.5

Gb/s per lane (2Gb/s data due to 8b/10b coding).
