P80C51FA-4B,557 Frequently Asked Questions (FAQ)

  • The P80C51FA-4B,557 can operate up to 40 MHz, but it's recommended to check the specific clock frequency requirements for your application and ensure that the crystal oscillator or external clock source can provide a stable clock signal within the recommended frequency range.

  • The UART baud rate can be configured using the Timer 1 in mode 2 (auto-reload mode) and the Baud Rate Generator (BRG) mode. The baud rate can be calculated using the formula: Baud Rate = (FOSC / 12) / (256 - TH1), where FOSC is the oscillator frequency and TH1 is the Timer 1 high byte.

  • Yes, the P80C51FA-4B,557 has an internal oscillator that can be used, but it's not recommended for applications that require high accuracy or stability. The internal oscillator frequency is not as accurate as an external crystal oscillator and may drift over time and temperature changes.

  • The P80C51FA-4B,557 has a built-in watchdog timer that can be enabled and configured using the WDTE (Watchdog Timer Enable) bit in the AUXR (Auxiliary Register) and the WDT (Watchdog Timer) register. The watchdog timer can be set to timeout after a specific period of inactivity, and can be reset using the WDTRST (Watchdog Timer Reset) instruction.

  • The maximum current that can be sourced or sunk by the I/O pins of the P80C51FA-4B,557 is 15 mA per pin, with a total current limit of 100 mA for all I/O pins combined. It's recommended to check the specific current requirements for your application and ensure that the I/O pins are not overloaded.
