PIC18F442 and PICF452 devices are now offered
in 44-pin, near chip scale micro lead frame pack-
ages (commonly known as “QFN”). This packag-
ing type has been added to the product line since
the latest revision of the Device Data Sheet.
The addition of this option requires the following
additions to the Device Data Sheet (DS39564B).
The referenced figures and tables follow this text.
1. The “Pin Diagrams” on pages 2-3 of the Data
2. Table 1-3 of Section 1.0 “Device Overview”
Sheet are amended with the addition of the
44-pin QFN pinout, shown in Figure 1.
is replaced with an updated version which
adds a column for QFN pin assignments. A row
is also added for previously unlisted NC pins.
All new information is indicated in bold.

System” (page 329), the “Package” options
are amended to include the new line item:
ML = QFN
that the package designation “MLF” is now
replaced by “QFN” in all occurrences through-
out the Device Data Sheet. “MLF” should be
considered an obsoleted term.
