The DS5003 secure microprocessor incorporates sophisticated security features including an array of mechanisms that are designed to resist all levels of threat, including observation, analysis, and physical attack. As a result, a massive effort is required to obtain any information about its memory contents. Furthermore, the "soft" nature of the DS5003 allows frequent modification of the secure information, thereby minimizing the value of any secure information obtained by such a massive effort. The device is an enhanced version of the DS5002FP secure microprocessor chip with additional scratchpad RAM.Note: Designers must have the following documents to fully use all the features of this device.
