PIN DESCRIPTIONS  
This input is used to synchronize the data transfer from  
and to the device.  
The descriptions of the pins are listed in Table 2-1.

Write-Protect (WP)  
Name PDIP SOIJ  
Function  
This pin must be connected to either VSS or VCC. If tied  
to VSS, write operations are enabled. If tied to VCC,  
write operations are inhibited, but read operations are  
not affected.

2.1  
A0, A1 Chip Address Inputs  
The A0 and A1 inputs are used by the 24XX1025 for  
multiple device operations. The levels on these inputs  
are compared with the corresponding bits in the slave  
address. The chip is selected if the comparison is true.  
Up to four devices may be connected to the same bus  
by using different Chip Select bit combinations. In most  
applications, the chip address inputs A0 and A1 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.  
2.2  
A2 Chip Address Input  
The A2 input is non-configurable Chip Select. This pin  
must be tied to VCC in order for this device to operate.  
2.3  
Serial Data (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 kΩ for 100 kHz, 2 kΩ for  
400 kHz and 1 MHz).  
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.
