Product Summary
The DS5250F-825 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 DS5250F-825 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. The applications of the DS5250F-825 include: PIN Pads, Financial Terminals, Applications that Require Data Security.
