*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

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.
