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.
