16.
for i = 16 to 127, T = -40°C to 125°C. Max( ) is the maximum value of the resistance and Min ( ) is
the minimum value of the resistance over the temperature range.
17. t

is the time from the end of a Write sequence of SPI serial interface, to the end of the self-timed internal non-volatile write cycle.
18. R
pu
is specified for the highest data rate transfer for the device. Higher value pull-up can be used at lower data rates.
