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.
