... The AT24C02B is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3) 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. Table 0-1. Pin Configuration ...

... DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the AT24C02B. As many as eight 2K devices may be addressed on a sin- gle bus system (device addressing is discussed in detail under the Device Addressing section). WRITE PROTECT (WP): The AT24C02B has a write protect pin that provides hardware data protection ...
