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.
