For applications where precise timing is not a
requirement, the RC oscillator option is available.
The operation and functionality of the RC oscillator
is dependent upon a number of variables. The RC
oscillator frequency is a function of:
• Supply voltage
• Resistor (R
• Operating temperature.
The oscillator frequency will vary from unit to unit
Two options are available for this oscillator mode
which allow RA4 to be used as a general purpose
I/O or to output F
due to normal process parameter variation. The
difference in lead frame capacitance between
package types will also affect the oscillation fre-
quency, especially for low C
also needs to account for the tolerance of the
external R and C components. Figure 9-5 shows
how the R/C combination is connected.
