The DS2252T Secure Microcontroller Module is 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 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 microcontroller while in-system. This allows frequent changing 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, analysis, and physical attack. As a result, a massive effort would be required to obtain any information about 1 of 15 |
