DS5250 Datasheet | Maxim Integrated

Rev 4; 11/08 ABRIDGED DATA SHEET EVAALVUAAILTAIOBNLEKIT High-Speed Secure Microcontroller General Description The DS5250 is a highly secure, four clocks-permachine cycle, 100% 8051-instruction-set-patible microprocessor in Maxim’s secure microcontroller family. 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 and optionally its data memory with a hardware-based single- or triple-DES (data encryption standard) algorithm, making it almost impossible to extract information. It also implements block cipher encoding that uses block addresses to modify the encrypted data, further strengthening security. This makes the device ideal for storage and transmission of passwords, personal identification numbers, encryption keys, and other highly confidential information.
