Notes
13.
These parameters are guaranteed by design. Production test equipment uses 4.16 MHz, 5.0V SPI interface.
14.
This parameter is guaranteed by design but not production tested.
15.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
16.
Time required for valid output status data to be available on the SO pin.
17.
Time required for output states data to be terminated at the SO pin.
18.
Time required to obtain valid data out from SO following the rise of SCLK with a 200pF load.
Table 5. Dynamic Electrical Characteristics
Characteristics noted under conditions of 3.0V
VDD 5.5V, 8.0V VPWR 28V, -40C TC 125C, unless otherwise noted.
Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 13 V, TA = 25C.
