Package Description
7
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.
