AMCC PowerPC 405EP

The LinuxLink software distribution model enables the usage of the AMCC405EP LinuxLink for development targeting all designs based on AMCC405EP processor.

Implemented in the scalable PowerPC Architecture^™, the 405EP processor maintains code compatibility with other PowerPC processors for ease in migration and fast time-to-market. An optimized balance of performance, low power, and features makes the PowerPC 405EP an ideal solution for communication, data storage, and pervasive computing applications.

Processor derivatives enabled:

The AMCC405EP LinuxLink can also be used as a starting point for Linux development for designs based on other processors in the 405 family.

Reference boards/OEM boards enabled:

The AMCC405EP LinuxLink can also be used as a starting point for Linux development for designs derived from:

Notes:

Complete peripheral support for AMCC405EP derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.

Processor Overview

The AMCC PowerPC 405EP 32-bit RISC processor is designed to provide a flexible, fast time-to-market hardware solution to satisfy the demands of high- performance embedded applications. Implemented in the scalable PowerPC Architecture^™, the 405EP processor maintains code compatibility with other PowerPC processors for ease in migration and fast time-to-market. An optimized balance of performance, low power, and features makes the PowerPC 405EP an ideal solution for communication, data storage, and pervasive computing applications.

The 405EP processor supports speeds of up to 333MHz and incorporates a rich mix of features, such as two Ethernet MACs, a PCI interface, an SDRAM Controller, and other on-chip peripherals. In addition, power management features, a small form factor, and low power consumption make the AMCC 405 processor family an ideal platform for applications ranging from networking to video.
