Note 1:
These parameters are characterized but not tested in manufacturing.
2:
Data in “Typ” column is at 5V, 25°C unless otherwise stated. Parameters are for design guidance only and
are not tested.
3:
The minimum clock period for SCK is 100 ns. Therefore, the clock generated in Master mode must not
violate this specification.
4:
Assumes 50 pF load on all SPI pins.
