PIC18F66K80 FAMILY
APPENDIX B: MIGRATION TO
PIC18F66K80 FAMILY
Devices in the PIC18F66K80, PIC18F4580,
PIC18F4680 and 18F8680 families are similar in their
functions and features. Code can be migrated from the
other families to the PIC18F66K80 without many
changes. The differences between the device families
are listed in Table B-1 and Table B-2. For more details
on migrating to the PIC18F66K80, refer to
“PIC18FXX80 to PIC18FXXK80 Migration Guide”
(DS39982).
