Note 1: Maximum pin capacitance = 10 pF for all I2Cx pins (for 1 MHz mode only).
Device must operate at a
minimum of 1.5 MHz
Device must operate at a
minimum of 10 MHz
Device must operate at a
minimum of 1.5 MHz
Device must operate at a
minimum of 10 MHz
CB is specified to be from
10 pF to 400 pF
CB is specified to be from
10 pF to 400 pF
Only relevant for Repeated
Start condition
After this period, the first
clock pulse is generated
Time the bus must be free
before a new transmission
can start
