FUNCTIONAL DESCRIPTION

2.1

Principles of Operation

The 11AA02UID 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 11AA02UID devices contain an 8-bit instruction

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 11AA02UID works as slave. Both master and slave

can operate as transmitter or receiver, but the master

device determines which mode is active.
