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 V_CCat Room

Temperature
