Description:
The Microchip Technology Inc. 11AA02UID device is a
2 Kbit Serial Electrically Erasable PROM with a
preprogrammed, 32-bit unique ID. The device is
organized in blocks of x8-bit memory and support the
patented* single I/O UNI/O® serial bus. By using
Manchester encoding techniques, the clock and data
are combined into a single, serial bit stream (SCIO),
where the clock signal is extracted by the receiver to
correctly decode the timing and value of each bit.
Low-voltage design permits operation down to 1.8V,
with standby and active currents of only 1 uA and 1 mA,
respectively.
The 11AA02UID is available in standard 8-lead SOIC
and 3-lead SOT-23 packages.

2.0 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
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 11AA02UID works as slave. Both master and slave
can operate as transmitter or receiver, but the master
device determines which mode is active.
