DESCRIPTION
The DS5002FP Secure Microprocessor Chip is a se-
cure version of the DS5001FP 128K Soft Microproces-
sor Chip. In addition to the memory and I/O enhance-
ments of the DS5001FP, the Secure Microprocessor
Chip incorporates the most sophisticated security fea-
tures available in any processor. The security features
of the DS5002FP include an array of mechanisms which
are designed to resist all levels of threat, including ob-
servation, analysis, and physical attack. As a result, a
massive effort would be required to obtain any informa-
tion about memory contents. Furthermore, the “soft” na-
ture of the DS5002FP allows frequent modification of
the secure information, thereby minimizing the value of
any secure information obtained by such a massive ef-
fort.
The DS5002FP implements a security system which is
an improved version of its predecessor, the DS5000FP.
Like the DS5000FP, the DS5002FP loads and executes
application software in encrypted form. Up to 128K x 8
bytes of standard SRAM can be accessed via its Byte–
wide bus. This RAM is converted by the DS5002FP into
lithium–backed nonvolatile storage for program and
data. Data is maintained for over 10 years at room tem-
perature with a very small lithium cell. As a result, the
contents of the RAM and the execution of the software
