7. PACKAGE MECHANICAL DATA
The following sections provide the package parameters and mechanical dimensions for the PC745B, 255 PBGA package as well as
the PC755B, 360 CBGA and PBGA packages. While both the PC755B plastic and the 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 pack-
ages for this device. For more information on designing a common footprint for both plastic and ceramic package types, please con-
tact your local Motorola sales office.
