5.6 Timing Requirements

MIN NOM MAX UNIT
fSCL Serial clock frequency 100 kHz
400
tHD;STA Hold time (repeated) START condition. After this period, the first clock pulse is generated. SCL = 100 kHz 4 µs
SCL = 400 kHz 600 ns
tLOW LOW period of the SCL clock SCL = 100 kHz 4.7 µs
SCL = 400 kHz 1.3
tHIGH HIGH period of the SCL clock SCL = 100 kHz 4 µs
SCL = 400 kHz(1) 1
tSU;STA Set-up time for a repeated START condition SCL = 100 kHz 4.7 µs
SCL = 400 kHz 600 ns
tHD;DAT Data hold time SCL = 100 kHz 0 3.45 µs
SCL = 400 kHz 0 900 ns
tSU;DAT Data set-up time SCL = 100 kHz 250 ns
SCL = 400 kHz 100
tr Rise time of both SDA and SCL signals SCL = 100 kHz 1000 ns
SCL = 400 kHz 300
tf Fall time of both SDA and SCL signals SCL = 100 kHz 300 ns
SCL = 400 kHz 300
tSU;STO Set-up time for STOP condition SCL = 100 kHz 4 µs
SCL = 400 kHz 600 ns
tBUF Bus free time between STOP and START condition SCL = 100 kHz 4.7 µs
SCL = 400 kHz 1.3
tSP Pulse width of spikes which must be suppressed by the input filter SCL = 100 kHz —(2) —(2) ns
SCL = 400 kHz 0 50
Cb Capacitive load for each bus line SCL = 100 kHz 400 pF
SCL = 400 kHz 400
(1) The SCL duty cycle at 400 kHz must be > 40%.
(2) The inputs of I2C devices in Standard-mode do not require spike suppression.
