MICROCHIP AT88SC1616C-MJ

The Atmel AT88SC1616C is a high-performance secure memory device offering 16-Kbits of user memory with advanced built-in security and cryptographic features. The user memory is divided into 16 zones of 128 bytes each, with individually configurable security access rights per zone, or effectively combined to provide space for 1 to 16 data files.

The device delivers high security, low cost, and ease of implementation without requiring a microprocessor operating system. The embedded cryptographic engine provides dynamic and symmetric mutual authentication between the device and host, as well as stream encryption of all data and passwords exchanged between the device and host. Up to four unique key sets can be used for these operations. The AT88SC1616C can communicate with virtually any smart card reader using the asynchronous T=0 protocol defined by ISO 7816-3 (Gemplus patent).

Through dynamic and symmetric mutual authentication, data encryption, and the use of cryptographic checksums, the AT88SC1616C provides a secure location for storing sensitive information within a system. With its tamper detection circuitry, this information remains secure even under attack. A 2-wire serial interface operating at 1.0MHz enables fast and efficient communication with up to 15 individually addressable devices. The AT88SC1616C is available in an industry-standard 8-pin package with the same pinout as 2-wire serial EEPROMs.
