VR and ZQ Packages—MPC8275 and MPC8270
The following gures and table represent the alternate 516 PBGA package. For information on the standard
package for the MPC8280 and the MPC8270, refer to Section 8.1, “ZU Package—MPC8280 and
Figure 15 shows the pinout of the VR and ZQ packages as viewed from the top surface.
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 4.3,
“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 ltering 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.
