Electrical Characteristics
Items on the same line have no ordering requirement with respect to one another. Items on separate lines
must be ordered sequentially such that voltage rails on a previous step must reach 90 percent of their value
before the voltage rails on the current step reach ten percent of theirs.
NOTE
If the items on line 2 must precede items on line 1, please ensure that the
delay does not exceed 500 ms and the power sequence is not done greater
than once per day in production environment.
NOTE
From a system standpoint, if the I/O power supplies ramp prior to the VDD
core supply, the I/Os on the MPC8541E may drive a logic one or zero during
power-up.
2.1.3 Recommended Operating Conditions
Table 2 provides the recommended operating conditions for the MPC8541E. Note that the values in
Table 2 are the recommended and tested operating conditions. Proper device operation outside of these
conditions is not guaranteed.
