LPC1313FHN33 datasheet by NXP Semiconductors

LPC1313FHN33 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be achieved with the internal oscillator?
  The internal oscillator can be configured to run up to 12 MHz, but the maximum clock frequency depends on the voltage and temperature range. At 3.3V and 25°C, the maximum clock frequency is around 10 MHz.
• How do I configure the pin multiplexing to use the desired peripherals?
  The pin multiplexing is configured using the PINSEL registers. Each peripheral function has a corresponding PINSEL register that needs to be set to enable the function on the desired pin. Refer to the user manual for the specific register settings.
• What is the minimum voltage required for the ADC to operate accurately?
  The ADC requires a minimum voltage of 2.4V to operate accurately. Below this voltage, the ADC may not provide reliable results.
• How do I implement a low-power mode with the LPC1313FHN33?
  The LPC1313FHN33 has several low-power modes, including Sleep, Deep Sleep, and Power-Down modes. These modes can be entered by configuring the PCON register and using the WFI (Wait For Interrupt) instruction. The user manual provides more details on how to implement these modes.
• Can I use the LPC1313FHN33 with an external crystal oscillator?
  Yes, the LPC1313FHN33 can be used with an external crystal oscillator. The external oscillator can be connected to the XTALIN and XTALOUT pins, and the clock source can be selected using the CLKSRC register.
