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.
