2 / 13 page AT24C02A/04A/08A 2 Block Diagram Pin Description SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open collector devices. DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the AT24C02A. As many as eight 2K devices may be addressed on a single bus system (device addressing is discussed in detail under the Device Addressing section). The AT24C04A uses the A2 and A1 inputs for hard wire addressing and a total of four 4K devices may be addressed on a single bus system. The A0 pin is a no con- nect. The AT24C08A only uses the A2 input for hardwire addr es si ng a nd a total of two 8K de vi ces ma y be addressed on a single bus system. The A0 and A1 pins are no connects. WRITE PROTECT (WP): The AT24C02A/04A/08A has a Write Protect pin that provides hardware data protection. The Write Protect pin allows normal read/write operations when connected to ground (GND). When the Write Protect Absolute Maximum Ratings* Operating Temperature .................................. -55 °C to +125°C *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age 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. Storage Temperature ..................................... -65 °C to +150°C Voltage on Any Pin with Respect to Ground .....................................-1.0V to +7.0V Maximum Operating Voltage........................................... 6.25V DC Output Current........................................................ 5.0 mA |
