AT24C02B General 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 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.

*NOTICE: Stresses beyond those listed under "Absolute
Maximum Ratings" may cause permanent damage
to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
