GENERAL DESCRIPTION
The DS5002FP secure microprocessor chip is a
secure version of the DS5001FP 128k soft
microprocessor chip. In addition to the memory and
I/O enhancements of the DS5001FP, the secure
microprocessor chip incorporates the most
sophisticated security features available in any
processor. The security features of the DS5002FP
include 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
memory contents. Furthermore, the “soft” nature of
the DS5002FP allows frequent modification of the
secure information, thereby minimizing the value of
any secure information obtained by such a massive
effort.
