APPENDIX B:

MIGRATION

BETWEEN HIGH-END

DEVICE FAMILIES

Devices in the PIC18F45J10 family and PIC18F4520

families are very similar in their functions and feature

sets. However, there are some potentially important

differences which should be considered when

migrating an application across device families to

achieve a new design goal. These are summarized in

Table B-1. The areas of difference which could be a

major impact on migration are discussed in greater

detail later in this section.
