SCK clock frequency fSCK − 3.5 − 5.0 − 6.5 MHz CS setup time during CS falling tCSS.CL 90 − 90 − 65 − ns CS setup time during CS rising tCSS.CH 90 − 90 − 65 − ns CS deselect time tCDS 160 − 140 − 110 − ns CS hold time during CS falling tCSH.CL 90 − 90 − 65 − ns CS hold time during CS rising tCSH.CH 90 − 90 − 65 − ns SCK clock time “H” *1 tHIGH 125 − 95 − 65 − ns SCK clock time “L” *1 tLOW 125 − 95 − 65 − ns Rising time of SCK clock *2 tRSK − 1 − 1 − 1 μs Falling time of SCK clock *2 tFSK − 1 − 1 − 1 μs SI data input setup time tDS 20 − 20 − 20 − ns SI data input hold time tDH 30 − 30 − 30 − ns SCK “L” hold time during HOLD rising tSKH.HH 70 − 70 − 45 − ns SCL “L” hold time during HOLD falling tSKH.HL 40 − 40 − 30 − ns SCK “L” setup time during HOLD falling tSKS.HL 0 − 0 − 0 − ns SCK “L” setup time during HOLD rising tSKS.HH 0 − 0 − 0 − ns Disable time of SO output *2 tOZ − 100 − 100 − 75 ns Delay time of SO output tOD − 120 − 90 − 60 ns Hold time of SO output tOH 0 − 0 − 0 − ns Rising time of SO output *2 tRO − 80 − 70 − 50 ns Falling time of SO output *2 tFO − 80 − 70 − 50 ns Disable time of SO output during HOLD falling *2 tOZ.HL − 100 − 100 − 75 ns Delay time of SO output during HOLD rising *2 tOD.HH − 80 − 80 − 60 ns WP setup time tWS1 0 − 0 − 0 − ns WP hold time tWH1 0 − 0 − 0 − ns WP release / setup time tWS2 0 − 0 − 0 − ns WP release / hold time tWH2 150 − 150 − 100 − ns *1. The clock cycle of the SCK clock (frequency fSCK) is 1/fSCK μs. This clock cycle is determined by a combination of several AC characteristics. Note that the clock cycle cannot be set as (1/fSCK) = tLOW (Min.) + tHIGH (Min.) by minimizing the SCK clock cycle time. *2. These are values of sample and not 100% tested. |
