Pin Description

SERIAL CLOCK (SCL): The SCL input is used to positive

edge clock data into each E

PROM device and negative

edge clock data out of each device.

SERIAL DATA (SDA): The SDA pin is bidirectional for se-

rial 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 AT24C01A and the AT24C02. As many as eight

1K/2K devices may be addressed on a single bus system

(device addressing is discussed in detail under the Device

Addressing section).

The AT24C04 uses the A2 and A1 inputs for hard wire

addressing and a total of four 4K devices may be ad-

dressed on a single bus system. The A0 pin is a no con-

nect.

The AT24C08 only uses the A2 input for hardwire ad-

dressing and a total of two 8K devices may be addressed

on a single bus system. The A0 and A1 pins are no con-

nects.

The AT24C16 does not use the device address pins which

limits the number of devices on a single bus to one. The

A0, A1 and A2 pins are no connects.
