This section details the power sequencing considerations for the MPC8358E.
2.2.1
MPC8358E does not require the core supply voltage (V
LV
supplies are stable and if the I/O voltages are supplied before the core voltage, there may be a period of
time that all input and output pins will actively be driven and cause contention and excessive current. In
order to avoid actively driving the I/O pins and to eliminate excessive current draw, apply the core voltage
