PIC18F442 and PICF452 devices are now offered
in 44-pin, near chip-scale micro lead frame
packages (commonly known as “QFN”). This
packaging 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.
The “Pin Diagrams” on pages 2-3 of the Data
Sheet are amended with the addition of the
44-pin QFN pinout, shown in Figure 1.
Table 1-3
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.

Section 24.1 “Package Marking Information”
is amended to include a marking template and
example for 44-pin QFN devices. These are
shown in Figure 1.
Section 24.2 “Package Details” is amended to
include the mechanical drawing of the 44-pin
QFN package following the existing drawings.
This is shown in Figure 2.
In the “PIC18FXX2 Product Identification
System” (page 329), the “Package” options are
amended to include the new line item:
ML = QFN
For the sake of completeness, it is also noted that
the package designation “MLF” is now replaced by
“QFN” in all occurrences throughout the Device
Data Sheet. “MLF” should be considered an
obsoleted term.
