Pin Configurations (continued)
Choosing Pullup Resistors
I2C requires pullup resistors to provide a logic-high
level to data and clock lines. There are tradeoffs
between power dissipation and speed, and a compro-
mise must be made in choosing pullup resistor values.
Every device connected to the bus introduces some
capacitance even when the device is not in operation.
I2C specifies 300ns rise times to go from low to high
(30% to 70%) for fast mode, which is defined for a data
rate of 400kbps (refer to I2C specifications for details).
In order to meet the rise time requirement, choose the
pullup resistors such that the rise time (tR =
0.85RPULLUP xCBUS) is less than 300ns. For a bus
capacitance of 400pF, choose a pullup resistor less
than 880
Ω. Often I2C devices work when the maximum
specified rise time is exceeded. However, if the rise
times become too slow, the devices on the bus do not
recognize the command signals. Optional resistors (24
Ω)
in series with SDA and SCL protect the device inputs
from high-voltage spikes on the bus lines and also mini-
mize crosstalk and undershoot of the bus signals.
