A0, A1, A2 Chip Address Inputs
2.3
Serial Clock (SCL)
The A0, A1 and A2 inputs are used by the 24XX32A for
multiple device operation. The levels on these inputs
are compared with the corresponding bits in the slave
The SCL input is used to synchronize the data transfer
to and from the device.
address. The chip is selected if the comparison is true.
2.4
Write-Protect (WP)
Up to eight devices may be connected to the same bus
by using different Chip Select bit combinations. These
inputs must be connected to either V CC or V SS .
In most applications, the chip address inputs A0, A1
and A2 are hard-wired to logic ‘ 0 ’ or logic ‘ 1 ’. For
applications in which these pins are controlled by a
microcontroller or other programmable device, the chip
address pins must be driven to logic ‘ 0 ’ or logic ‘ 1 ’
before normal device operation can proceed. Address
pins are not available in the SOT-23 and chip scale
packages.
This pin must be connected to either V SS or V CC . If tied
to V SS , write operations are enabled. If tied to V CC ,
write operations are inhibited but read operations are
not affected.
2.2
Serial Data (SDA)
SDA is a bidirectional pin used to transfer addresses
and data into and out of the device. It is an open-drain
terminal, therefore, the SDA bus requires a pull-up
resistor to V CC (typical 10 k ? for 100 kHz, 2 k ?? for
400 kHz)
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating Start and Stop conditions.
