These parameters are guaranteed by design. Production test equipment uses 4.16MHz, 5.0V SPI interface.
This parameter is guaranteed by design but not production tested.
Rise and Fall time of incoming SI,
CS
, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
Time required for valid output status data to be available on SO pin.
Time required for output states data to be terminated at SO pin.
Time required to obtain valid data out from SO following the rise of SCLK with 200pF load.
