Unique Identifier Line
Each Unique Identifier memory device (IIT, IIK or IIP models) ships with a unique, 48-bit serial number. We also offer OEMs the option of having their own unique OEM code. Both the OEM code and serial number are non-changeable. In addition to this read-only information, the devices contain 1.5 Kb of re-writeable non-volatile memory.
CryptoMemory® keys and tokens utilize Microchip CryptoMemory ICs. We offer CryptoMemory keys and tokens with memory capacities from 1 Kb to 256 Kb. When connected to an authorized host, the device and host will mutually authenticate each other. Only after this takes place can encrypted communications occur.

More Than Just a Serial Number
Our Unique Identifier memory keys and tokens do contain a serial number that is guaranteed to be unique, but that’s not what makes this product unique. It is the 1.5 Kb of re-writable, non-volatile memory that make these products a much more powerful credential than read-only devices like mag-stripe cards or RFID badges. Here is just a sampling of ways to use our Unique Identifier memory devices:
Use an IIT memory token as the credential. The serial number identifies the user and is used to encrypt the data. The encrypted data includes a PIN that the user must enter at the device. You must possess the token and know the password to gain access. With the PIN stored on the device, the embedded device does not need to be constantly updated as new users are added.
ID with Audit Trail
Let’s say you make a vending machine, parking meter, ticket machine or any other electronically-controlled device that collects cash. At some point, someone must collect that cash and hopefully transfer all of it to the proper facility. You can use an IIT token to gain access to the money. The microcontroller validates the ID, but then also records on the token the amount money removed. When the deposit is made, the token is used to ensure the full amount is deposited.
These are just a couple of the possible applications for our Secure Memory products. Check out our Applications Page for more ideas.
