NOTES for Figure 58

All dimensions are in millimeters.

Dimensions and tolerances per ASME Y14.5M-1994.

Maximum solder ball diameter measured parallel to datum A.

Datum A, the seating plane, is defined by the spherical crowns of the solder balls.

Capacitors may not be present on all devices.

Caution must be taken not to short capacitors or expose metal capacitor pads on package top.

All dimensions symmetrical about centerlines unless otherwise specified.

Note that for MPC8640 (single core) the solder balls for the following signals/pins are not populated in the

package: VDD_Core1 (R16, R18, R20, T17, T19, T21, T23, U16, U18, U22, V17, V19, V21, V23, W16,

W18, W20, W22, Y17, Y19, Y21, Y23, AA16, AA18, AA20, AA22, AB23, AC24) and SENSEVDD_Core1

(U20).
