Oscillator Configurations
9.2.1
OSCILLATOR TYPES
The PIC16C432 can be operated in four different
oscillator
options.
The
user
can
program
two
configuration bits (FOSC1 and FOSC0) to select one of
these four modes:
LP - Low Power Crystal
XT - Crystal/Resonator
HS - High Speed Crystal/Resonator
RC - Resistor/Capacitor
9.2.2
CRYSTAL OSCILLATOR/CERAMIC
RESONATORS
In XT, LP or HS modes, a crystal or ceramic resonator
is connected to the OSC1 and OSC2 pins to establish
oscillation (Figure 9-1). The PIC16C432 oscillator
design requires the use of a parallel cut crystal. Use of
a series cut crystal may give a frequency out of the
crystal manufacturers specifications. When in XT, LP or
HS modes, the device can have an external clock
source to drive the OSC1 pin (Figure 9-2).

See Table 9-1 and Table 9-2 for recom-
mended values of C1 and C2.
2: A series resistor may be required for AT strip
cut crystals.

Note 1: Recommended values of C1 and C2 are
indentical to the ranges tested table.
2: Higher capacitance increases the stability
of oscillator, but also increases the start-
up time.
3: Since each resonator/crystal has its own
characteristics, the user should consult
the resonator/crystal manufacturer for
appropriate values of external compo-
nents.
4: Rs may be required in HS mode, as well
as XT mode, to avoid over driving crystals
with low drive level specification.
