Oscillator Configurations
7.2.1
OSCILLATOR TYPES
The PIC16C505 can be operated in four different
oscillator
modes.
The user can program three
configuration bits (FOSC<2:0>) to select one of these
four modes:
LP:
Low Power Crystal
XT:
Crystal/Resonator
HS:
High Speed Crystal/Resonator
INTRC: Internal 4 MHz Oscillator
EXTRC: External Resistor/Capacitor
7.2.2
CRYSTAL OSCILLATOR / CERAMIC
RESONATORS
In HS, XT or LP modes, a crystal or ceramic resonator
is connected to the RB5/OSC1/CLKIN and RB4/
OSC2/CLKOUT
pins
to
establish
oscillation
(Figure 7-1).
The
PIC16C505
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 HS, XT
or LP modes, the device can have an external clock
source drive the RB5/OSC1/CLKIN pin (Figure 7-2).

These values are for design guidance only. Rs may
be required to avoid overdriving crystals with low
drive level specification. Since each crystal has its
own characteristics, the user should consult the crys-
tal manufacturer for appropriate values of external
components.
