Atmel AT24C02B Serial EEPROM Datasheet

The document describes the features and characteristics of the AT24C02B product. The product is a serial electrically erasable and programmable read-only memory (EEPROM) with low power and low voltage operation. It is organized as 2048 bits of 256 words of 8 bits each. It features a two-wire serial interface, Schmitt trigger, filtered inputs for noise suppression, bidirectional data transfer protocol, and compatibility with different voltage levels. The product supports hardware data protection with a write protect pin, 8-byte (2K) and partial page write modes, and has a high reliability with 1 million write cycles and 100 years of data retention. It is available in various package types including 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. Suitable for many industrial and commercial applications.
