LPC2131FBD64,151 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the LPC2131?
  The maximum clock frequency for the LPC2131 is 60 MHz, but it can be overclocked up to 70 MHz with some limitations.
• How do I configure the pin multiplexing on the LPC2131?
  The pin multiplexing on the LPC2131 can be configured using the PINSEL registers. Each peripheral function has a corresponding PINSEL register that determines which pins are used for that function.
• What is the minimum voltage required for the LPC2131 to operate?
  The minimum voltage required for the LPC2131 to operate is 2.4V, but it is recommended to use a voltage of at least 3.0V for reliable operation.
• How do I use the ADC on the LPC2131?
  The ADC on the LPC2131 can be used by configuring the ADC registers, selecting the input channel, and starting the conversion. The ADC result can be read from the ADGDR register.
• Can I use the LPC2131 with an external crystal oscillator?
  Yes, the LPC2131 can be used with an external crystal oscillator. The external crystal oscillator can be connected to the XTAL1 and XTAL2 pins, and the PLL can be configured to use the external clock source.
