Description
The AT24C01A/02SC/04SC/08SC/16SC provide 1024/2048/4096/8192/16384 bits of
serial, electrically-erasable, and programmable read-only memory (EEPROM) orga-
nized as 128/256/512/1024/2048 words of 8 bits each. The devices are optimized for
use in smart card applications where low-power and low-voltage operation may be
essential. The devices are available in several standard ISO 7816 smart card modules
(see
Ordering Information,
pages 12鈥?3). All devices are functionally equivalent to
Atmel serial EEPROM products offered in standard IC packages (PDIP, SOIC, TSSOP,
MAP), with the exception of the slave address and write protect functions, which are
not required for smart card applications.
