PACKAGE OUTLINE
DESCRIPTION
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
