Description
The AT24C512SC provides 524,288 bits of serial electrically erasable and
programmable read only memory (EEPROM) organized as 65,536 words of 8 bits
each. This device is optimized for use in smart card applications where low-power and
low-voltage operation may be essential. This device is available in a standard ISO
7816 smart card module (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.
