Secure Microprocessor Chip

DS503

General Description

Features

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 fre-

quent 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.

Differences from the DS5002FP

The DS5003 implements only one additional feature

from the DS5002FP: it adds 128 bytes of internal

scratchpad memory (for a total of 256 bytes) similar to

that used in 8032/8052 architectures. This additional

memory is accessible through indirect addressing 8051

instructions such as “mov a, @r1,” where r1 now can

have a value between 0 and 255. It is also usable as

stack space for pushes, pops, calls, and returns.

♦ Crash-Proof Operation

scratchpad RAM locations above 7Fh. It can also be

used to reach the lower RAM (0h–7Fh) if needed. The

address is supplied by the contents of the working reg-

ister specified in the instruction. Thus, one instruction

can be used to reach many values by altering the con-

tents of the designated working register. Note that only

R0 and R1 can be used as pointers. An example of reg-

ister indirect addressing is as follows:
