I2C I/O DC Parameters
NOTE
See the errata for HS-I2C in i.MX51 Chip Errata document. The two
standard I2C modules have no errata.
The DC Electrical Characteristics listed below are guaranteed using operating ranges per Table 13, unless
otherwise noted.

To maintain a valid level, the transitioning edge of the input must sustain a constant slew rate (monotonic) from the current DC
level through to the target DC level, VIL or VIH. Monotonic input transition time is from 0.1 ns to 1 s.
2 Overshoot and undershoot conditions (transitions above OVDD and below OVSS) on switching pads must be held below 0.6
V, and the duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/undershoot must
be controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other
methods. Non-compliance to this specification may affect device reliability or cause permanent damage to the device.
3 Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.
4 I/O leakage currents are listed in Table 25.
