ABRIDGED DATA SHEET  
Rev 4; 11/08  
High-Speed Secure Microcontroller  
DS250  
In-Application Programmable Through User Software  
Allows Self-Modification of Program/Data Memory  
General Description  
The DS5250 is a highly secure, four clocks-per-  
machine cycle, 100% 8051-instruction-set-compatible  
microprocessor in Maxim’s secure microcontroller fami-  
ly. 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 sin-  
gle- 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 iden-  
tification numbers, encryption keys, and other highly  
confidential information.  
Four 8-Bit Ports/One 6-Bit Port  
Three 16-Bit Timer/Counters  
256 Bytes of Scratchpad RAM  
♦ Advanced Features  
CRC-16/32 Generator  
5KB Internal SRAM (Optional 1KB Stack)  
Single or 3DES Engine  
Partitionable Memory Segments Variable from 4KB to  
256KB  
♦ High-Speed Architecture  
Four Clocks-per-Machine Cycle  
DC-to-25MHz Operation  
Single-Cycle Instruction in 160ns  
Dual Data Pointers Can Increment or Decrement  
Independently  
Automatic Data Pointer (DPTR) Selection Available  
Programmable Speed MOVX Instructions  
1KB On-Chip Instruction Cache  
Applications  
PIN Pads  
Financial Terminals
