2. Description
The AT88SC1608 provides 17,408 bits of serial
EEPROM memory organized as one configuration zone
of 128 bytes and eight user zones of 256 bytes each.
This device is optimized as a “secure memory” for the
smart card market, secure identification for electronic
data transfer, or components in a system, without the
requirement of an internal microprocessor.
