AT88SC0104C-SI

EEPROM Serial-2Wire 1Kbit 256 x 4 3.3V/5V 8Pin SOIC

Description

The AT88SC0104C member of the CryptoMemory® family is a high-performance secure memory providing 1 Kbit of user memory with advanced security and cryptographic features built in. The user memory is divided into four 32-byte zones, each of which may be individually set with different security access rights or combined together to provide space for 1 to 4 data files.
