CryptoMemory® Secure EEPROM Storage
The Datakey CryptoMemory® line of portable memory devices utilize Microchip’s CryptoMemory® ICs and are offered in both the key and SlimLine™ token form factors.
Note: CryptoMemory is a mature product line. For new applications, see the CryptoAuthentication™ line.
CryptoMemory® Token Series
Our most popular form factor
- Low-cost Board-mount Receptacles
- IP-rated Panel-mount Receptacles
- 2-wire (I2C) Interface
- 1 Kb to 256 Kb Capacity
Not Recommended for New Designs / Microchip has classified the CryptoMemory® ICs as "mature". While not EOL, we would recommend that new designs consider the newer CryptoAuthentication™ memory tokens.
CryptoMemory Security Features
CryptoMemory devices feature a variety of security features:
- Mutual authentication between host and device
- Encrypted communication across bus after authentication
- Password-protected memory zones
- Locking of memory zone after too many invalid passwords
- Tamper protection circuits
ID with Audit Trail
Consider vending machines, parking meters, ticket machines 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. A secure memory device with a unique serial number can be used to gain access to the money. The microcontroller validates the serial number (and entered password/PIN/biometric data), but then also securely records on the token the amount money removed. When the deposit is made, the token is used to ensure the full amount is deposited.
