FUNCTIONAL DESCRIPTION  
Principles of Operation  
The 11XX family of serial EEPROMs support the  
UNI/O® protocol. They can be interfaced with  
microcontrollers, including Microchip’s PIC® microcon-  
trollers, ASICs, or any other device with an available  
discrete I/O line that can be configured properly to  
match the UNI/O protocol.  
The 11XX devices contain an 8-bit instruction register.  
The devices are accessed via the SCIO pin.  
Table 4-1 contains a list of the possible instruction  
bytes and format for device operation. All instructions,  
addresses, and data are transferred MSb first, LSb  
last.  
Data is embedded into the I/O stream through  
Manchester encoding. The bus is controlled by a  
master device which determines the clock period, con-  
trols the bus access and initiates all operations, while  
the 11XX works as slave. Both master and slave can  
operate as transmitter or receiver, but the master  
device determines which mode is active.
