PIC16F74 and PIC16F77 devices are now offered
in a 44-pin, micro lead frame package (commonly
known as “QFN”). This provides near chip scale
package size. This option is in addition to the 28-pin
QFN packages already available for the PIC16F73
and PIC16F76 devices. The 44-pin QFN package
has been added to the product line since the
original publication of the Device Data Sheet.
The addition of this option requires the following
additions to the Device Data Sheet (DS30325B).
Referenced figures and tables follow this text.

replaced with an updated version which adds a
column for QFN pin assignments. All new
information is indicated in bold.

For the sake of completeness, it is also noted
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.
