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
addressing and a total of two 8K devices may 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
