Western Digital MyBook World Edition Internals

MyBook is powered by OnSemi OXE800SE ARM9 chip.

OnSemi OXE800SE features

The OXE800SE is a highly integrated device for network attached storage products. Optimized for consumer applications, the OXE800SE integrates an Ethernet MAC, three USB host ports and a SATA host controller. The device requires a minimal number of external components thereby providing OEMs with the right balance between performance and cost of ownership. Supporting real-time encryption to the Advanced Encryption Standard (AES), the OXE800SE ensures sensitive personal data are kept secure and protected. In addition the PCI interface enables simple system expansion to support wireless network clients.

Based around the world-renowned ARM9 processor, the OXE800SE runs the Linux OS to ensure development of customer specific features and applications is both simple and rapid. In addition Oxford Semiconductor provides a comprehensive support package including evaluation boards, a software development kit as well as configuration and production utilities to minimize time to market.
