2.1 PCB Hardware Changes for the 100-Pin PZ, 80-Pin PNA and 64-Pin PM Packages

This section describes the F28003x and F28P55x differences that exist between the 100-Pin PZ, 80-Pin PNA and 64-Pin PZ packages.

100-Pin PZ: There are increased mux options on many analog pins on the F28P55x vs the F28003x. There is an additional 2 GPIOs on F28P55x that replace 2 power pins on the F28003x. Figure 2-1 outlines the differences.

80-Pin PN/PNA: There are increased mux options on many analog pins on the F28P55x vs the F28003x. There are an additional 2 GPIOs on F28P55x that replace 2 power pins on the F28003x. There is one less GPIO on the F28P55x due to the VREGENZ pin. Please note that the package pitch is changed with the F28003x having a 0.5mm pin pitch and the F28P55x having a 0.4mm pin pitch. Figure 2-2 outline the differences.

64-Pin PM: There are increased mux options on many analog pins on the F28P55x vs the F28003x. There is an additional 2 GPIOs on F28P55x that replace 2 power pins on the F28003x. There is one less GPIO on the F28P55x vs the F28003x Q100 variant due to the VREGENZ pin. Figure 2-3 outlines the differences.
