Notes

15.

Upper and lower logic threshold voltage range applies to SI, CS, SCLK, RST, IN, and WAKE input signals. The WAKE and RST signals may be

supplied by a derived voltage reference to VPWR.

16.

No hysteresis on FSI and wake pins. Parameter is guaranteed by process monitoring but is not production tested.

17.

Input capacitance of SI, CS, SCLK, RST, and WAKE. This parameter is guaranteed by process monitoring but is not production tested.

18.

The current must be limited by a series resistance when using voltages > 7.0 V.

19.

Pull-up current is with CS OPEN. CS has an active internal pull-up to VDD.
