DS5250

High-Speed Secure Microcontroller

GENERAL DESCRIPTION

Cꢀ Advanced Features

The DS5250 is a highly secure, 4 clocks-per-machine

cycle, 100% 8051-instruction-set-compatible

microprocessor in the Secure Microcontroller family

from Dallas Semiconductor. It was designed to be the

cryptographic engine of PIN pads, financial terminals,

and any other application in which data security is

paramount. A key feature of the device is that it

encrypts its program memory with a hardware-based

single or triple (3) DES (data encryption standard)

algorithm, making it nearly impossible to extract

information. Another DES (3DES) hardware block is

available to the user for encrypting arbitrary information

in data memory space. This makes the device ideal for

storage and transmission of passwords, personal

identification numbers, encryption keys, and other highly

confidential information.
