Block Diagram

Notes: 1.

When the ORG pin is connected to VCC, the x16 organization is selected. When it is connected to ground,

the x8 organization is selected. If the ORG pin is left unconnected and the application does not load the input

beyond the capability of the internal 1M

 pull-up resistor, then the x16 organization is selected.

2.

If the x16 organization is the mode of choice and pin 6 (ORG) is left unconnected, Atmel recommends using

AT93C46E device. For more details, see the AT93C46E datasheet.
