Freescale Semiconductor
At recommended operating conditions with NVDD of 3.3 V ± 300 mv
All values refer to V
Input current (0 V ≤V
Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. C
3. See the MPC8315E PowerQUICC II Pro Integrated Host Processor Reference Manual for information on the digital filter
4. I/O pins obstruct the SDA and SCL lines if NVDD is switched off.
SCL clock frequency
Low period of the SCL clock
High period of the SCL clock
Setup time for a repeated START condition
Hold time (repeated) START condition (after this period, the first clock pulse is
generated)
Data setup time
Data hold time:
Fall time of both SDA and SCL signals
Setup time for STOP condition
Bus free time between a STOP and START condition
Noise margin at the LOW level for each connected device (including hysteresis)
