2.1  
A0, A1 and A2 Chip Address  
Inputs  
2.3  
Serial Clock (SCL)  
This input is used to synchronize the data transfer from  
and to the device.  
The A0, A1 and A2 inputs are used by the 24XX512 for  
multiple device operations. The logic levels on these  
inputs are compared with the corresponding bits in the  
slave address. The chip is selected if the compare is  
true.  
2.4  
Write-Protect (WP)  
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.  
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 VCC or VSS.  
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 logic device,  
the chip address pins must be driven to logic ‘0’ or logic  
‘1’ before normal device operation can proceed.  
3.0  
FUNCTIONAL DESCRIPTION  
The 24XX512 supports a bidirectional 2-wire bus and  
data transmission protocol. A device that sends data  
onto the bus is defined as a transmitter and a device  
receiving data as a receiver. The bus must be  
controlled by a master device which generates the  
Serial Clock (SCL), controls the bus access and  
generates the Start and Stop conditions, while the  
24XX512 works as a slave. Both master and slave  
can operate as a transmitter or receiver, but the  
master device determines which mode is activated.  
2.2  
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 kfor 100 kHz, 2 k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.
