Limits are based on characterization results; not production tested.
The CS , SCLK, SDI, and SDO pins are not internally pulled up or down; they must be driven for proper operation.
Limits are based on characterization results; not production tested.
The timing values are measured corresponding to the input thresholds (V
Output rise and fall times are measured with a capacitive load of 150 pF.

Description
SPI clock frequency
1/(SPI clock frequency) mark-space ratio for the SCLK input is 40/60 to 60/40
CS falling edge to SCLK falling edge
SCLK rising edge to CS rising edge
CS rising edge to SDO disabled
CS deassertion between SPI communications
SCLK low pulse width (space)
SCLK high pulse width (mark)
SDI valid before SCLK rising edge
SDI valid after SCLK rising edge
SCLK falling edge to SDO/SDIO output transition
SDO/SDIO output low to output high transition
SDO/SDIO output high to output low transition
