GENERAL DESCRIPTION
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.
