Note:
When the ORG pin is connected to VCC, the “x 16” organization is selected. When it is
connected to ground, the “x 8” organization is selected. If the ORG pin is left uncon-
nected and the application does not load the input beyond the capability of the internal 1
Meg ohm pullup, then the “x 16” organization is selected. The feature is not available on
the 1.8V devices.
For the AT93C46, if “x 16” organization is the mode of choice and Pin 6 (ORG) is left
unconnected, Atmel recommends using the AT93C46A device. For more details, see the
AT93C46A datasheet.
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only, and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability
