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 iden-
tification for electronic data transfer, or components in a system without the
requirement of an internal microprocessor.
