Serial Clock (SCL)
The A0, A1 and A2 inputs are used by the 24XX64 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
from and to the device.

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
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.

FUNCTIONAL DESCRIPTION
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 or Chip Scale
packages.
The 24XX64 supports a bidirectional, 2-wire bus and
data transmission protocol. A device that sends data
onto the bus is defined as transmitter, while a device
receiving data is defined as a receiver. The bus has to

Serial Data (SDA)
be controlled by a master device which generates the
Serial Clock (SCL), controls the bus access and
SDA is a bidirectional pin used to transfer addresses
and data into and out of the device. Since it is an open-
drain terminal, 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 the Start and Stop conditions.

generates the Start and Stop conditions, while the
24XX64 works as slave. Both master and slave can
operate as transmitter or receiver, but the master
device determines which mode is activated.
