AT88SC25616C CryptoMemory Smart Card
The AT88SC25616C, part of the CryptoMemory family, is a memory solution offering 256 Kbits of user memory. It incorporates security features and encryption capabilities. The user memory is divided into 16 zones, each with 2 bytes. These zones can be individually configured with security access rights and combined to accommodate 1 to 4 data files.
In terms of card applications the AT88SC25616C offers levels of security while being cost effective and easy to implement without requiring a microprocessor operating system. It includes a engine that enables dynamic and symmetric mutual authentication, between the device and host. Additionally it performs stream encryption for all exchanged data and passwords. Up to four unique key sets can be utilized for these operations. The AT88SC25616C supports communication with any card reader by using the asynchronous T = 0 protocol specified in ISO 7816 3. Communication speeds up to 153,600 baud can be achieved by leveraging ISO 7816 3 Protocol and Parameter Selection.
In embedded applications the AT88SC25616C provides a solution, for storing information within a system through dynamic symmetric mutual authentication, data encryption and encrypted checksums. Its tamper detection circuits ensure that this information remains safeguarded under attack.
The AT88SC25616C utilizes a 2 wire interface operating at 1.5 MHz, for speedy communication, with a maximum of 15 devices that can be specifically addressed. It is conveniently packaged in industry 8 lead packages, featuring the well known pinout as other 2 wire serial EEPROMs.
