PIC18F448-I/L Frequently Asked Questions (FAQs)

  • The PIC18F448-I/L can operate at a maximum clock frequency of 40 MHz, but it can also be overclocked to 48 MHz with some limitations.
  • The oscillator configuration is done through the FOSC2:FOSC0 bits in the CONFIG3H register. The oscillator can be configured for HS (high-speed), XT (crystal), or EC (external clock) modes.
  • The PIC18F448-I/L can source up to 25 mA and sink up to 40 mA on its I/O pins, but it's recommended to limit the current to 20 mA to ensure reliable operation.
  • The internal oscillator can be enabled by setting the INTOSC bit in the OSCCON register. The oscillator frequency can be selected by setting the IRCF bits in the OSCCON register.
  • The PLL is used to multiply the oscillator frequency by 4, allowing the microcontroller to operate at higher frequencies while still using a lower-frequency oscillator.
