1
Should be tied to VDDH via a 2K
Ω external pull-up resistor.
2
The default configuration of the CPM pins (PA[0–31], PB[4–31], PC[0–31], PD[4–31]) is input. To prevent excessive
DC current, it is recommended to either pull unused pins to GND or VDDH, or to configure them as outputs.
3
Must be pulled down or left floating.
4
If PCI is not desired, must be pulled up or left floating.
5
Sphere is not connected to die.
6
GNDSYN (AB1): This pin exists as a separate ground signal in MPC826x(A) devices; it does not exist as a separate
ground signal on the MPC8280. New designs must connect AB1 to GND and follow the suggestions in Section 4.6,
“Layout Practices.” Old designs in which the MPC8280 is used as a drop-in replacement can leave the pin connected
to GND with the noise filtering capacitors.
7
XFC (AB2) pin: This pin is used in MPC826x(A) devices; it is not used in MPC8280 because there is no need for
external capacitor to operate the PLL. New designs should connect AB2 (XFC) pin to GND. Old designs in which the
MPC8280 is used as a drop-in replacement can leave the pin connected to the current capacitor.

Symbol
Meaning
OVERBAR
Signals with overbars, such as TA, are active low.
UTM
Indicates that a signal is part of the UTOPIA master interface.
UTS
Indicates that a signal is part of the UTOPIA slave interface.
