AT24C02B-TH-T

AT24C02B-TH-T Datasheet

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.
