This section provides design considerations for the MPC885/MPC880 power supply. The
MPC885/MPC880 has a core voltage (V
voltage than the I/O voltage V
V
The signals PA[0:15], PB[14:31], PC[4:15], PD[3:15], TDI, TDO, TCK, TRST_B, TMS, MII_TXEN, and
MII_MDIO are 5 V tolerant. All inputs cannot be more than 2.5 V greater than V
tolerant pins cannot exceed 5.5 V and remaining input pins cannot exceed 3.465 V. This restriction applies
to power up/down and normal operation.
One consequence of multiple power supplies is that when power is initially applied the voltage rails ramp
up at different rates. The rates depend on the nature of the power supply, the type of load on each power
supply, and the manner in which different voltages are derived. The following restrictions apply:
These cautions are necessary for the long-term reliability of the part. If they are violated, the electrostatic
discharge (ESD) protection diodes are forward-biased, and excessive current can flow through these
diodes. If the system power supply design does not control the voltage sequencing, the circuit shown
