IIT Series Memory Tokens

Datakey IIT Unique Identifier memory tokens provide 1.5 Kbits of EEPROM along with a unique, non-changeable serial number. IIT memory tokens have an 2-wire (I2C) serial interface and can be written to/read from via a Datakey SlimLink™ Programmer or any microcontroller. The EEPROM in the IIT token has a unique factory-embedded serial number that cannot be changed by the user. The unique serial number can be used to prevent duplication of tokens by using the serial number as a unique encryption seed or by having the host system store a list of authorized serial numbers. The memory is solid over-molded using a rugged composite that protects the embedded memory from harsh environmental influences.
