Two-wire Serial EEPROM
1.
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 AT24C04B uses the A2 and A1 inputs for hard wire addressing and a
toal of four 4K devices may be addressed on a single bus system. The A0 pin is a no connect and can be connected to
ground (device addressing is discussed in detail under the Device Addressing section).
The AT24C08B only uses the A2 input for hardware addressing and a total of two 8K devices may be addressed on a
single bus system. The A0 and A1 pins are no connects and can be connected to ground (device addressing is
discussed in detail under the Device Addressing section).
