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 Atmel
addressing is discussed in detail under the Device Addressing section).
WRITE PROTECT (WP): AT24C02C 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 pin is
connected to V
