DESCRIPTION
The DS2252T is an 8051 compatible microcontroller
based on nonvolatile RAM technology. It is designed for
systems that need to protect memory contents from dis-
closure. This includes key data, sensitive algorithms,
and proprietary information of all types. Like other mem-
bers of the Secure Microcontroller family, it provides full
compatibility with the 8051 instruction set, timers, serial
port, and parallel I/O ports. By using NV RAM instead of
ROM, the user can program, then reprogram the micro-
controller while in–system. This allows frequent chang-
ing of sensitive processes with minimal effort. The
DS2252T provides an array of mechanisms to prevent
an attacker from examining the memory. It is designed
to resist all levels of threat including observation, analy-
sis, and physical attack. As a result, a massive effort
would be required to obtain any information about
memory contents. Furthermore, the “Soft” nature of the
DS2252T allows frequent modification of secure
information. This minimizes that value of any informa-
tion that is obtained.
