2.1.1 100-Pin PZ Migration for Existing PCB

If the PCB is already designed and you are moving from F28004x/F28003x to F28003x/F28004x respectively, dual routing is not possible and hence those pins become incompatible between the two devices, Table 2-1 outlines the migration.

For the color legend, see Figure 2-1.
