1 This characteristic is for 2.6-V output and 5-V input friendly pins.
2 VDATAPC is the maximum voltage the data pins can have been precharged to by an external device when the
MPC565/MPC566 data pins turn on as outputs. The 3.1-V maximum for VDATAPC is to allow the data pins to be driven
from an external memory running at a higher voltage. Note that if the data pins are precharged to higher than VDDL,
then the 50-pF maximum load characteristic must be observed.
3 The predischarge circuit is enabled by setting the PREDIS_EN bit to a “1” in the PDMCR2 register. VDATAPC is the
maximum voltage the data pins can have been precharged to by an external device when the MPC565/MPC566 data
pins turn on as outputs. The 5.25-V maximum for VDATAPC is to allow the data pins to be driven from an external
memory running at a higher voltage. Note that if the data pins are precharged to higher than VDDL, then the maximum
load characteristic must match the data bus drive setting and the data bus can withstand up to 3.6 volts for a cumulative
time of 24 hours over the lifetime of the device.
4 This characteristic is for 5-V output and 5-V input pins.
5 0.3V > V
DDA or VDDH, whichever is greater.
6 Within this range, no significant injection will be seen. See QADC64 Disruptive Input Current (I
NA).
