PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 8-1.
TABLE 8-1:
PIN FUNCTION TABLE
8.1
A0, A1, A2
The levels on these inputs are compared with the
corresponding bits in the slave address. The chip is
selected if the compare is true.
Up to eight 24XXX52 devices may be connected to the
same
bus
by
using

combinations. These inputs must be connected to
either VSS or VCC.
8.2
Serial Address/Data Input/Output
(SDA)
This is a bidirectional pin used to transfer addresses
and data into and data out of the device. It is an open
drain terminal. Therefore, the SDA bus requires a pull-
up resistor to VCC (typical 10 k
Ω for 100 kHz, 2 kΩ 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.
8.3
Serial Clock (SCL)
This input is used to synchronize the data transfer to
and from the device.
8.4
Write-Protect (WP)
This is the hardware write-protect pin. It can be tied to
VCC or VSS. If tied to VCC, the hardware write protection
is enabled. If the WP pin is tied to VSS, the hardware
write protection is disabled.
