LPC11D14FBD100/302 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 PINSELx registers, where x is the port number. Each bit in the register corresponds to a specific pin, and the value written to the bit determines the peripheral function assigned to that pin.
• What is the minimum voltage required for the ADC to operate accurately?
  The ADC requires a minimum voltage of 2.4V to operate accurately, but it's recommended to use a voltage of at least 2.7V for optimal performance.
• How do I implement a low-power mode to reduce power consumption?
  The LPC11D14FBD100/302 has several low-power modes, including Sleep, Deep Sleep, and Power-Down. These modes can be entered by configuring the PCON and PDSR registers, and can be woken up by interrupts or other events.
• 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, but the total current sourced or sunk by all pins should not exceed 100mA.
