Description

The AT24C01A/02SC/04SC/08SC/16SC provides 1024/2048/4096/8192/16384 bits

of serial, electrically-erasable and programmable read-only memory (EEPROM)

organized 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). The entire family is available in both high-voltage (4.5V to

5.5V) and low-voltage (2.7V to 5.5V) versions. All devices are functionally equivalent

to Atmel serial EEPROM products offered in standard IC packages (PDIP, SOIC,

EIAJ, LAP), with the exception of the slave address and Write Protect functions, which

are not required for smart card applications.
