29.1 Introduction
29.2 Features
29.3 Contact Information
Security is a generalized architecture consisting of Boot ROM, laser fuses and proprietary
circuitry for secure hardware initialization. In the context of this environment, the chip
supports multiple digital-rights-management content-protection from several security
vendors, (such as Microsoft and InterTrust). It exceeds all the requirements set forth by the
Secure Digital Music Initiative and allows for protection of object code as well as content.
Key features include:
