337-BGA ZWT Application to 256-BGA ZEJ or 169-BGA NMR

F2837x BGA pinout is only available in 337-BGA ZWT pinout. In F28P65x, BGA pinout is available in both 256 ZEJ and 169 NMR package outlines. There is obviously no board reusability when switching from F2837x BGA to F28P65x BGA due to the different package types involved so a new board design is required. Table 2-8 provides the comparison of the available digital channels and Table 2-9 shows the analog channels while Table 2-10 summarizes the available resources on the different BGA packages for both F2837x and F28P65x devices. Use these tables as references in planning pin resources when designing new schematics/boards for F28P65x BGA devices. In general, there will be more available flexible analog and digital pins in either the F28P65x 256 or 169 BGA compared to the F2837x BGA package.
