DS5003 Secure Microprocessor Chip
●General Description
■The DS5003 secure microprocessor incorporates sophisticated security features including an array of mechanisms that are designed to resist all levels of threat, including observation, analysis, and physical attack. As a result, a massive effort is required to obtain any information about its memory contents.Furthermore, the "soft" nature of the DS5003 allows frequent modification of the secure information, thereby minimizing the value of any secure information obtained by such a massive effort. The device is an enhanced version of the DS5002FP secure microprocessor chip with additional scratchpad RAM.
●Features
■8051-Compatible Microprocessor for Secure/Sensitive Applications
▲Access 32kB, 64kB, or 128kB of Nonvolatile SRAM for Program and/or Data Storage 128 Bytes of RAM128 Bytes of Indirect Scratchpad RAM In-System Programming Through On-Chip Serial Port Can Modify Its Own Program or Data Memory in the End System
■Firmware Security Features
▲Memory Stored in Encrypted Form Encryption Using On-Chip 64-Bit Key Automatic True Random-Key Generator Self-Destruct Input (SDI)Top Coating Prevents Microprobing Protects Memory Contents from Piracy
■Crash-Proof Operation
▲Maintains All Nonvolatile Resources for Over 10 Years (at Room Temperature) in the Absence of Power Power-Fail Reset Early Warning Power-Fail Interrupt Watchdog Timer
