DS2252T  
Soft Microcontroller Module  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS2252T secure microcontroller module is 8051-Compatible Microcontroller  
an 8051-compatible microcontroller based on  
nonvolatile RAM technology. It is designed for  
systems that need to protect memory contents  
from disclosure. This includes key data, sensitive  
algorithms, and proprietary information of all  
types. Like other members of the secure  
8, 32, or 64kbytes of Nonvolatile SRAM for  
Program and/or Data Memory Storage  
In-System Programming via On-Chip Serial  
Port  
Capable of Modifying its Own Program  
and/or Data Memory in the End System  
microcontroller family, it provides full Firmware Security Features  
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 microcontroller  
while in-system. This allows frequent changing of  
sensitive processes with minimal effort.  
Memory Stored in Encrypted Form  
Encryption Using On-Chip 64-Bit Key  
Automatic True Random Key Generator  
Self-Destruct Input (SDI)  
Improved Security Over Previous Generations  
Protects Memory Contents from Piracy  
Crashproof Operation  
Maintains All Nonvolatile Resources Up to  
10 Years in the Absence of VCC at Room  
Temperature
