2.1.2 100-Pin PZ Migration for New PCB Design

If the PCB is yet to be designed and you are moving from F28004x/F28003x to F28003x/F28004x, respectively, the dual routing technique illustrated in Figure 2-2 maximizes pin utilization. The complete pin migration is outlined in Table 2-2.

For the color legend, see Figure 2-1.
