The 24AA32A/24LC32A from Microchip Technology Inc. is a 32-KB I²C™-compatible serial EEPROM. The module is organised as a single block of 4K x 8-bit memory with a 2-wire serial interface. Low-voltage design allows operation up to 1.7 V with standby and active currents of only 1 µA/1 mA. It is designed for advanced low-power applications such as personal communication or data collection. The 24XX32A also has a page writing function for up to 32 bytes of data. Up to eight devices can be connected to the same bus via functional address lines, which enables an address space of up to 256 Kbits
