for i = 16 to 127, T = -40°C to 85°C. Max( ) is the maximum value of the resistance and Min ( ) is the minimum value of the resistance over the
temperature range.
13. This parameter is not 100% tested.
14. t
WC
is the minimum cycle time to be allowed for any non-volatile Write by the user, unless Acknowledge Polling is used. It is the time from a
valid STOP condition at the end of a Write sequence of a 3-wire serial interface Write operation, to the end of the self-timed internal non-volatile
write cycle.
