Comparison between V-Package and U-Package version
This series of microcontrollers comprise of the older V-package version and the newer
U-package version. In the newer U-package version, a Code Option NRM is added
and various features such as Crystal mode Operating frequency range, IRC mode
wake-up time, WDT Time-out time, Comparator function and Pins function have been
modified to favorably meet users’ requirements. The following table is provided for
quick comparison between the two package version and for user convenience in the
choice of the most suitable product for their application.
