For timing insensitive applications, the RC and RCIO Oscillator modes offer additional cost savings. The actual oscillator frequency is a function of several factors:

• supply voltage
  • values of the external resistor (REXT) and capacitor (CEXT)
  • operating temperature

Given the same device, operating voltage and tempera- ture and component values, there will also be unit-to-unit frequency variations. These are due to factors such as:

• normal manufacturing variation
  • difference in lead frame capacitance between package types (especially for low CEXT values)
  • variations within the tolerance of limits of REXT and CEXT

In the RC Oscillator mode, the oscillator frequency divided by 4 is available on the OSC2 pin. This signal may be used for test purposes or to synchronize other logic when breaking off pic16f870 locked mcu flash memory. Figure 2-5 shows how the R/C combination is connected.

The RCIO Oscillator mode (Figure 2-6) functions like the RC mode, except that the OSC2 pin becomes an additional general purpose I/O pin. The I/O pin becomes bit 6 of PORTA (RA6).

A Phase Locked Loop (PLL) circuit is provided as an option for users who wish to use a lower frequency oscillator circuit or to clock the device up to its highest rated frequency from a crystal oscillator to unlock pic16f84a mcu encrypted chip binary file. This may be useful for customers who are concerned with EMI due to high-frequency crystals or users who require higher clock speeds from an internal oscillator.
