Complete peripheral support for AMCC405GP 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 405GP 32-bit RISC processor is designed to provide a flexible hardware solution to satisfy the demands of high-performance embedded applications. Implemented in the scalable PowerPC architecture, the 405GP processor maintains code compatibility with other PowerPC processors for ease in migration and faster time-to-market. An optimized balance of performance, low power, and features makes them ideal solutions for communication, data storage, and pervasive computing applications.
The 405GP processor supports speeds of up to 266MHz and incorporates a rich mix of features, such as a PCI interface, an SDRAM Controller, a 64-bit on-chip CoreConnect bus, Ethernet and other on-chip peripheral support, and the IBM CodePack™ code compression engine. 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.
