FUNCTIONAL DESCRIPTION
Principles of Operation
The 11AA02E48 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 11AA02E48 devices contain an 8-bit instruction
register. The devices are accessed via the SCIO pin.
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 11AA02E48 works as slave. Both master and
slave can operate as transmitter or receiver, but the
master device determines which mode is active.
