The External Resistor-Capacitor (RC) modes support the use of an external RC circuit. This allows the designer maximum flexibility in frequency choice while keeping costs to a minimum when clock accuracy is not required. There are two modes, RC and RCIO. In RC mode, the RC circuit connects to the OSC1 pin. The OSC2/CLKOUT pin outputs the RC oscillator frequency divided by 4. This signal may be used to provide a clock for external circuitry, synchronization, calibration, test or other application requirements. Figure 3-5 shows the RC mode connections.

In RCIO mode, the RC circuit is connected to the OSC1 pin. The OSC2 pin becomes an additional general purpose I/O pin. The I/O pin becomes bit 4 of PORTA (RA4). Figure 3-6 shows the RCIO mode connections to clone electronic pcb board gerber file. The RC oscillator frequency is a function of the supply voltage, the resistor (REXT) and capacitor (CEXT) values and the operating temperature. Other factors affecting the oscillator frequency are:

packaging variations in capacitance

The user also needs to take into account variation due to tolerance of external RC components used.

The PIC16F688 has two independent, internal oscillators that can be configured or selected as the system clock source.

The HFINTOSC (High-Frequency Internal Oscillator) is factory calibrated and operates at 8 The frequency of the HFINTOSC can be user adjusted ±12% via software using the OSCTUNE register (Register 3-1).

The LFINTOSC (Low-Frequency Internal Oscillator) is uncalibrated and operates at approximately 31

The system clock speed can be selected via software using the Internal Oscillator Frequency Select (IRCF) bits.

The system clock can be selected between external or internal clock sources via the System Clock Selection (SCS) bit (see Section 3.5 “Clock Switching”).
