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.
