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.
