PIC18F458 → PIC18F4580 Migration
DEVICE MIGRATIONS
The PIC18F4580 is an extended architecture based on the PIC18F458 family, but offers many new features. This
document is intended to describe the functional differences, configuration differences and the electrical specification
differences that are present when migrating from one device to the next.
Table 1 summarizes the features that may have migration impact on the software code developed for PIC18F458.
Table 2 lists the new and modified features of PIC18F4580 that should not have any migration impact. Table 3 and
Table 4 summarize the differences in SFRs and configuration memory, respectively. Table 5 summarizes the differences
in specific DC characteristics.
The descriptions in the tables explain the difference
