MB91460D Series

15.7.4 I2C AC Timings at VDD5 = 3.0 to 5.5 V

• Conditions during AC measurements

All AC tests were measured under the following conditions:

-IOdrive = 3 mA

-VDD5 = 3.0 V to 5.5 V, Iload = 3 mA (VDD = 4.5 V to 5.5 V for MB91F467Dx)

-VSS5 = 0 V

-Ta =

 40°C to  105°C

-Cl = 50 pF

- VOL = 0.3 × VDD5

- VOH = 0.7 × VDD5

- EPILR = 0, PILR = 0 (CMOS Hysteresis 0.3 × VDD5/0.7 × VDD5)

Fast mode:

(VDD5 = 3.5 V to 5.5 V, VSS5 = AVSS5 = 0 V, TA = 40°C to  105°C)

*1 : On MB91F467Dx only guaranteed for 4.5 V < VDD5 < 5.5 V.

*2 : The noise filter will suppress single spikes with a pulse width of 0ns and between (1 to 1.5) cycles of peripheral clock, depending

on the phase relationship between I2C signals (SDA, SCL) and peripheral clock.

Note: tCLKP is the cycle time of the peripheral clock.
