For timing insensitive applications, the “RC” device
option offers additional cost savings. The RC oscillator
frequency is a function of the supply voltage, the resis-
tor (R
ing temperature. The oscillator frequency will vary from
unit to unit due to normal process variation. The differ-
ence in lead frame capacitance between package
types will also affect the oscillation frequency, espe-
cially for low C
into account variation due to tolerance of external R
and C components used. Figure 13-3 shows how the
R/C combination is connected to the PIC16CXX.
The oscillator frequency, divided by 4, is available on
the OSC2/CLKOUT pin, and can be used for test pur-
poses or to synchronize other logic (see Figure 3-2 for
waveform).
