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,  
andproprietaryinformationofalltypes. Likeothermem-  
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 NVRAM 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.  
Improved security over previous generations  
Protects memory contents from piracy  
Crashproof Operation  
Maintains all nonvolatile resources for over 10  
years in the absence of power  
Power–fail Reset  
Early Warning Power–fail Interrupt  
Watchdog Timer  
Precision reference for power monitor  
Fully 8051 Compatible  
128 bytes scratchpad RAM  
Two timer/counters  
On–chip serial port  
32 parallel I/O port pins  
Permanently powered real time clock
