Description

The DS5230 is a highly secure, four clocks-per-machine cycle, 100% 8051-instruction-set-compatible microprocessor in the secure microcontroller family from Maxim Integrated Products. It is a feature-reduced and cost-reduced version of the popular DS5250 high-speed secure microcontroller. Its proven architecture protects embedded application software and data against reverse engineering or cloning. A key feature of the device is that it encrypts its program memory with a hardware-based single- or triple-DES (data encryption standard) algorithm and provides optional data memory encryption, 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.

Note: Designers must have the following documents to fully use all the features of this device. This data sheet contains pin descriptions, feature overviews, and electrical specifications. Errata sheets contain deviations from published specifications. The user's guides offer detailed information about device features and operation.
