Description  
The AT24C02B provides 2048 bits of serial electrically erasable and programmable  
read-only memory (EEPROM) organized as 256 words of 8 bits each. The device is  
optimized for use in many industrial and commercial applications where low-power  
and low-voltage operation are essential. The AT24C02B is available in space-saving  
8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), 5-lead  
SOT23, 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire  
serial interface. In addition, the AT24C02B is available in 1.8V (1.8V to 5.5V) version.
