Protected Memory IC's for chip cards offer an economical way to manage and secure your application data. Protected memories are economical & frequently the best choice for a wide range of applications including loyalty, membership, ID, vending, and many others were some data protection is required.

Unlike serial memories, protected memory chips allow the user to write protect data stored on the card.  Each protected memory chip design employs several different security features to protect card data. Protected memories are common in applications were the fraud potential does not require encryption and the amount of data to be stored is small.

With the exception of Atmel's new AT88SC1616C, protected memories all use proprietary protocols developed on a chip by chip basis before the PCSC standard for smartcard reader drivers was developed. This means that protected memories are not normally compatible with smartcard readers using PCSC drivers.  However, you will find that most reader manufactures have written proprietary drivers for customers using protected memories.

Because the protocol changes from one protected memory to another, finding development tools generally means first deciding on a reader and then asking its manufacturer for the development tools you will need. All the memories listed here are compatible with the ACR 30 reader which can be purchased with the Developers Kit.

The AT88SC1608 provides 17,408 bits of serial EEPROM memory organized as one configuration zone of 128 bytes and eight user zones of 256 bytes each. This device is optimized as a "secure memory" for smartcard applications without the requirement of an internal microprocessor.

NEW! The AT88SC1616C member of the CryptoMemory family is a high performance secure memory providing 16 Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into 16 zones, each of which may be individually set with different security access rights or combined together to provide pace for 1 to 16 data files. The AT88SC1616C provides high security, low cost and ease of implementation for smartcard applications without the need for a microprocessor operation system.
