14.3 SPI-bus timing characteristics

[1]

No load value; bus will be held up by bus capacitance; use RC time constant with application values.

Fig 52. I2C-bus timing

Table 51.

SPI-bus timing characteristics

VDD1, VDD2, VDD3 = 2.5 V to 5.5 V; VSS1 = 0 V; VLCD = 4.0 V to 12.0 V; Tamb = 40 C to +105 C; unless otherwise specified.

All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to VIL and

VIH with an input voltage swing of VSS1 to VDD1.
