Package Description
The following sections provide the package parameters and mechanical dimensions for the MPC745, 255 PBGA
package, as well as the MPC755, 360 CBGA and PBGA packages. While both the MPC755 plastic and ceramic
packages are described here, both packages are not guaranteed to be available at the same time. All new designs
should allow for either ceramic or plastic BGA packages for this device. For more information on designing a
common footprint for both plastic and ceramic package types, see the
Freescale Flip-Chip Plastic Ball Grid Array
Presentation
. The MPC755 was initially sampled in a CBGA package, but production units are currently provided
in both a CBGA and a PBGA package. Because of the better long-term device-to-board interconnect reliability of
the PBGA package, Freescale recommends use of a PBGA package except where circumstances dictate use of a
CBGA package.

Notes:
1. OV
DD
supplies power to the processor bus, JTAG, and all control signals except the L2 cache controls (L2CE, L2WE, and L2ZZ); L2OV
DD
supplies power to the L2 cache interface (L2ADDR[0:16], L2DATA[0:63], L2DP[0:7], and L2SYNC_OUT) and the L2 control signals; and V
DD
supplies power to the processor core and the PLL and DLL (after filtering to become AV
DD
and L2AV
DD
, respectively). These columns serve
as a reference for the nominal voltage supported on a given signal as selected by the BVSEL/L2VSEL pin configurations of
Table 2
and the
voltage supplied. For actual recommended value of V
in
or supply voltages, see
Table 3
.
2. These are test signals for factory use only and must be pulled up to OV
DD
for normal machine operation.
3. This pin must be pulled up to OV
DD
for proper operation of the processor interface. To allow for future I/O voltage changes, provide the option
to connect BVSEL independently to either OV
DD
or GND.
4. These pins are reserved for potential future use as additional L2 address pins.
5. Uses one of nine existing no connects in the MPC750, 360 BGA package.
6. Internal pull-up on die.
7. This pin must be pulled up to L2OV
DD
for proper operation of the processor interface. To allow for future I/O voltage changes, provide the
option to connect L2VSEL independently to either L2OV
DD
or GND.
8. Internally tied to L2OV
DD
in the MPC755, 360 BGA package to indicate the power present at the L2 cache interface. This signal is not a power
supply input.
Caution:
This differs from the MPC745, 255 BGA package.
