Note:
- CMOSen =
0
must only be used when VCC is between 2.0V and 5.5V and the host is running on a lower supply voltage than the client. In this mode, the input buffers are referenced to an internal supply and VIL and VIH levels are independent of the external VCC supply over this range. For voltages lower than 2.0V, CMOSen must always be set to ‘1
’. - The lowest system current will be achieved if the inputs are driven to VCC or allowed to be pulled up to VCC by the pull-up resistors on the signal lines.
- Applies to all commands where an EEPROM write does not occur.
- Applies to all commands where an
EEPROM write occurs. This includes
Write
,Lock
,GenKey
,Counter(Increment)
. - This condition is characterized but not production tested.
