PARAMETER TEST CONDITIONS MIN NOM MAX UNIT
ƒSPI SPI clock (SCLK) frequency CSDO = 30 pF, IO protection resistor 0.47 kΩ 8 MHz
thigh High time: SCLK logic high-time duration 45 ns
tlow Low time: SCLK logic low-time duration 45 ns
tsucs CS setup time: time delay between falling edge of CS and rising edge of SCLK 45 ns
tsu_SDI SDI setup time: setup time of SDI before the falling edge of SCLK 15 ns
th_SDI SDI hold time: hold time of SDI before the falling edge of SCLK 30 ns
td_SDO Delay time: time delay from rising edge of SCLK to data valid at SDO 30 ns
thcs Hold time: time between the falling edge of SCLK and rising edge of CS 45 ns
tdis_cs CS disable time, CS high to SDO high impedance 10 ns
thics SPI transfer inactive time (time between two transfers) during which CS must remain high 500 ns
