PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
9.1
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices provide seven
system clock options:
• Fast RC (FRC) Oscillator
• FRC Oscillator with Phase Locked Loop (PLL)
• Primary (XT, HS or EC) Oscillator
• Primary Oscillator with PLL
• Secondary (LP) Oscillator
• Low-Power RC (LPRC) Oscillator
• FRC Oscillator with postscaler
9.1.1
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optionally specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.
The primary oscillator can use one of the following as
its clock source:
• Crystal (XT): Crystals and ceramic resonators in
• High-Speed Crystal (HS): Crystals in the range of
• External Clock (EC): External clock signal is
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
The Low-Power RC (LPRC) internal oscIllator runs at a
nominal frequency of 32.768 kHz. It is also used as a
reference clock by the Watchdog Timer (WDT) and
Fail-Safe Clock Monitor (FSCM).
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip PLL
to provide a wide range of output frequencies for device
operation.
