LPC2142FBD64,151 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the LPC2142?
  The maximum clock frequency for the LPC2142 is 60 MHz, but it can be overclocked up to 70 MHz with some limitations.
• How do I configure the pin multiplexing on the LPC2142?
  The pin multiplexing on the LPC2142 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 purpose of the bootloader in the LPC2142?
  The bootloader in the LPC2142 is used to load the application code into the flash memory. It can be used to update the firmware in the field or to load a new application code.
• How do I use the ADC on the LPC2142?
  The ADC on the LPC2142 can be used by configuring the ADC registers, selecting the analog input channel, and starting the conversion. The ADC result can be read from the ADCR register.
• What is the power consumption of the LPC2142?
  The power consumption of the LPC2142 depends on the clock frequency, voltage, and operating mode. In active mode, the typical current consumption is around 20 mA at 3.3V and 48 MHz.
