Serial Clock (SCL)
The SCL input is used to clock all data into
and out of the device.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer
data into and out of the device. It is an
open drain output and may be wire–ORed
with any number of open drain or open
collector outputs.

This feature allows the user to assign the

Device Selection Input – A1 (as
Appropriate)
This input serves as a chip select signal to
an EEPROM when multiple EEPROMs are
present on the same IIC bus. These inputs,
if present, should be connected to V
CC
or
V
SS
in a unique manner to enable proper
selection of an EEPROM among multiple
EEPROMs.
During a typical addressing sequence,
every EEPROM on the IIC bus compares
the configuration of these inputs to the
respective two MSBs of the Device/Page
Block selection information (which is part of
the Slave address) to determine a valid
selection. For example, if the two MSB bits
of the Device/Page Block selection are 0-0,
the EEPROM whose Device Selection
input (A1) is connected to the respective
V
SS
is selected.
On the SA24C1024, only A1 is provided,
so the corresponding A2 bit in the
Device/Page Block selection should be set
to 0 during all accesses to the device.
These two pins have a weak internal
pulldown circuit.
