Oscillator Configurations
9.2.1
OSCILLATOR TYPES
The PIC16C433 can be operated in seven different
oscillator modes. The user can program three configu-
ration bits (FOSC<2:0>) to select one of these seven
modes:
LP:
Low Power Crystal
HS:
High Speed Crystal/Resonator
XT:
Crystal/Resonator
INTRC*:
Internal 4 MHz Oscillator
EXTRC*: External Resistor/Capacitor
*Can be configured to support CLKOUT
9.2.2
CRYSTAL OSCILLATOR/CERAMIC
RESONATORS
In XT, HS or LP modes, a crystal or ceramic resonator
is connected to the GP5/OSC1/CLKIN and GP4/OSC2
pins
to
establish
oscillation
The
PIC16C433 oscillator design requires the use of a par-
allel cut crystal. Use of a series cut crystal may give a
frequency out of the crystal manufacturers specifica-
tions. When in XT, HS or LP modes, the device can
have an external clock source drive the GP5/OSC1/
CLKIN pin (Figure 9-2).

Note 1:
See Capacitor Selection tables for
recommended values of C1 and C2.
2: A series resistor (R
S) may be required for AT
strip cut crystals.
3: RF varies with the Oscillator mode selected
(approx. value = 10 M
).

These values are for design guidance only. RS may
be required in HS mode, as well as XT mode, to
avoid overdriving crystals with low drive level specifi-
cation. Since each crystal has its own characteristics,
the user should consult the crystal manufacturer for
appropriate values of external components.
