Note:
The internal 4MHz oscillation frequencies shown in
above are provided for design guidance only and not tested
or guaranteed. The user needs to take into account that the
internal oscillation of the MC80F0308 may show different
frequency with sample by sample, voltage and tempera-
ture. The internal oscillation can be used only in timing in-
sensitive application.
7.7 Typical Characteristics (MC80C0304/08/16)
These graphs and tables provided in this section are for design
guidance only and are not tested or guaranteed.
In some graphs or tables the data presented are out-
side specified operating range (e.g. outside specified
V
DD
range). This is for information only and devices
are guaranteed to operate properly only within the
specified range.
The data presented in this section is a statistical summary of data
collected on units from different lots over a period of time. “Typ-
ical” represents the mean of the distribution while “max” or
“min” represents (mean + 3
σ
) and (mean
−
3
σ
) respectively
where
σ
is standard deviation
