Low-voltage design permits operation R/W Control VSS down to 1.8 volts for the 24AA00 version, and every version maintains a maximum standby current of only Pin Function Table 1 A and typical active current of only 500 A. This device was designed for where a small amount of Name Function EEPROM is needed for the storage of calibration VSS Ground values, ID numbers or manufacturing information, etc. SDA Serial Data The 24XX00 is available in 8-pin PDIP, 8-pin SOIC (150 mil), 8-pin TSSOP, 8-pin 2x3 DFN and the 5-pin SCL Serial Clock SOT-23 packages.
