1.4Overview

The IXP45X/IXP46X network processors are highly integrated devices, capable of interfacing with most common industry standard peripherals, required for high- performance control applications.

Note: This document discusses all features supported on the Intel® IXP465 Network Processor. A subset of these features is supported by certain processors in the IXP45X/ IXP46X product line, such as the Intel® IXP460 or Intel® IXP455 network processors. For details on feature support listed by processor, see the Intel® IXP45X and Intel® IXP46X Product Line of Network Processors Datasheet.

Some of the key features of the IXP45X/IXP46X network processors, when used as a single-chip solution for embedded applications, are as follows:

Intel XScale® Processor (compliant with Intel® StrongARM* architecture) — Up to 667 MHz
