Clock frequency F
CLK — 100 — 400 kHz
Clock high time T
HIGH 4000 — 600 — ns
Clock low time TLOW 4700 — 1300 — ns
SDA and SCL rise time TR — 1000 — 300 ns (Note 1)
SDA and SCL fall time T
F — 300 — 300 ns (Note 1)
Start condition hold time THD:STA 4000 — 600 — ns After this period, the first
clock pulse is generated
Start condition setup time T
SU:STA 4700 — 600 — ns Only relevant for repeated
Start condition
Data input hold time T
HD:DAT 0—0—ns(Note 2)
Data input setup time TSU:DAT 250 — 100 — ns
Stop condition setup time T
SU:STO 4000 — 600 — ns
Output valid from clock TAA — 3500 — 900 ns (Note 2)
Bus free time TBUF 4700 — 1300 — ns Time the bus must be free
before a new transmission

Endurance 1M — 1M — cycles 25°C, (Note 4)
Note 1: Not 100% tested. C
B = total capacitance of one bus line in pF.
2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
3: The combined T
SP and VHYS specifications are due to Schmitt Trigger inputs which provide improved
noise spike suppression. This eliminates the need for a TI specification for standard operation.
4: This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ Model which can be downloaded at
www.microchip.com.
