Figure 1. SPI - Timing Requirements in Host Mode
Table 1. SPI - Timing Specifications in Host Mode
Symbol Description Min. Typ.✝ Max. Unit Condition
fSCK * SCK clock frequency 10 MHz  
TSCK * SCK period 100 ns  
tSCKW SCK high/low width 0.5×TSCK ns  
tSCKR SCK rise time 2.7 ns  
tSCKF SCK fall time 2.7 ns  
tMIS MISO setup to SCK 10 ns  
tMIH MISO hold after SCK 10 ns  
tMOS MOSI setup to SCK 0.5×TSCK ns  
tMOH MOSI hold after SCK 1.0 ns  

Data in the “Typ.” column is at TA = 25°C and VDD = 3.0V unless otherwise specified. These parameters are not tested and are for design guidance only.

* These parameters are characterized but not tested in production.
