Description:
The Microchip Technology Inc. 11AA02E48 device is a
2 Kbit Serial Electrically Erasable PROM. The device is
organized in blocks of x8-bit memory and support the
patented* single I/O UNI/O
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 11AA02E48 is available in standard 8-lead SOIC
and 3-lead SOT-23 packages.

PRE-PROGRAMMED EUI-48™ NODE ADDRESS The 11AA02E48 is programmed at the factory with a globally unique, EUI-48™ and EUI-64™ compatible node address stored in the upper 1/4 of the array and write-protected through the STATUS register. The remaining 1,536 bits are available for application use. ...
