PARAMETER
The internal oscillator may be used with an external quartz crystal or ceramic resonator as described
in
ceramic resonator part numbers for commercial temperature applications. At this time, the ceramic
resonator does not offer sufficient temperature stability to operate over the industrial temperature
range.
