Description

The AT88SC153 provides 2,048 bits of serial EEPROM memory organized as one configuration zone of 64 bytes and three user zones of 64 bytes each. This device is optimized as a "secure memory" for multiapplication smart card markets, secure identification for electronic data transfer,or components in a system without the requirement of an internal microprocessor.

The embedded authentication protocol allows the memory and the host to authenticate each other. When this device is used with a host that incorporates a microcontroller (e.g.,AT88SC153 AT89C51, AT89C2051, AT90S1200), the system provides an "anti-wiretapping" configuration. The device and the host exchange "challenges" issued from a random generator and verify their values through a specific cryptographic function included in each part. When both agree on the same result, the access to the memory is permitted.
