EEPROM Serial-2Wire 1Kbit 256 x 4 3.3V/5V 8Pin M2 - J Module
**Description**
The AT88SC0104CA 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 effectively combined together to provide space for 1 to 4 data files. The AT88SC0104CA features an enhanced command set that allows direct communication with microcontroller hardware 2-Wire interface thereby allowing for faster firmware development with reduced code space requirements.
