80-pin packages. Block diagrams for the two groups
are shown in Figure 1-1.
The devices are differentiated in that PIC18F86J72
devices have a Flash program memory of 64 Kbytes
and PIC18F87J72 devices memory is 128 Kbytes
All other features for the devices are identical. These
are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2.
