85C72/82/92  
9.0  
PIN DESCRIPTION  
9.1  
A0, A1 and A2 Chip Address Inputs  
The levels on these inputs are compared with the cor-  
responding bits in the slave address. The chip is  
selected if the compare is true. For 85C92, A0 is no  
function.  
Up to eight 85C72/82s or four 85C92s can be con-  
nected to the bus.  
These inputs must be connected to either VSS or VCC.  
9.2  
SDASerialAddress/DataInput/Output  
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 pullup  
resistor to VCC (typical 10KW). For normal data trans-  
fer SDA is allowed to change only during SCL LOW.  
Changes during SCL HIGH are reserved for indicating  
the START and STOP conditions.  
9.3  
SCL Serial Clock  
This input is used to synchronize the data transfer from  
and to the device.  
9.4  
NC No Connect  
This pin can be left open or used as a tie point.  
Note 1: A “page” is defined as the maximum num-  
ber of bytes that can be programmed in a  
single write cycle. The 85C72/82 page is  
2 bytes long and the 85C92 page is 8  
bytes long.  
Note 2: A “block” is defined as a continuous area  
of memory with distinct boundaries. The  
address pointer can not cross the bound-  
ary from one block to another. It will, how-  
ever, wrap around from the end of a block  
to the first location in the same block. The  
85C72/82 has only one block (256 bytes),  
while the 85C92 has two blocks of 256  
bytes each.
