PPC460GTx

High-Bandwidth SoC Embedded Processor

Benefits

Delivers 800 MHz to 1.2 GHz performance for embedded I/O processor designs.

Offers a powerful mix of high bandwidth, design flexibility, and robust features.

Two Gen 2 PCI Express interfaces, an on-chip DDR2 SDRAM controller, network encryption engine, and a rich peripheral mix.

Ideally suited for network and wireless infrastructure, and general purpose control plane applications.
