LPC11U24FBD64/401 datasheet by NXP Semiconductors

LPC11U24FBD64/401 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 50 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 device to operate?
  The LPC11U24FBD64/401 can operate down to 1.8V, but the recommended operating voltage is 2.4V to 3.6V for optimal performance.
• How do I use the ADC in differential mode?
  To use the ADC in differential mode, configure the ADC channel to use the differential input pins (e.g., AD0.1 and AD0.0 for channel 0) and set the ADC mode to differential mode using the ADCR register. Also, ensure that the input signals are within the specified common-mode voltage range.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 4mA per pin, with a total current limit of 100mA for all GPIO pins combined.
