The maximum setup times specified for the 33991 is the minimum time needed from the microcontroller to guarantee correct operation.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
This value is for a 1 MHz calibrated internal clock; it will change proportionally as the internal clock frequency changes.
Time required for output status data to be available for use at SO. 1 K
load on SO.
Time required for output status data to be terminated at SO. 1 K
load on SO.
Time required to obtain valid data out from SO following the rise of SCLK.
T
he device shall meet all SPI interface-timing requirements specified in the
SPI Interface Timing
, over the temperature range specified in the
environmental requirements section. Digital Interface timing is based on a symmetrical 50 percent duty cycle SCLK Clock Period of 333 ns. The
device shall be fully functional for slower clock speeds.
