Notes

13.

Upper and lower logic threshold voltage range applies to SI, CS, SCLK, RST, IN[0:3], and WAKE input signals. The WAKE and RST

signals may be supplied by a derived voltage referenced to VPWR.

14.

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

15.

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

16.

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

17.

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

18.

The selection of the RFS must take into consideration the tolerance, temperature coefficient and lifetime duration to assure that the

resistance value will always be within the desired (specified) range.

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 6.0V

≤ VPWR ≤ 27V, 4.5V ≤ VDD ≤ 5.5V, -40°C ≤ TA ≤ 125°C, GND = 0V, unless

otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless

otherwise noted.
