LPC1102LVUKZ datasheet by NXP Semiconductors

LPC1102LVUKZ 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. According to the datasheet, the maximum clock frequency is 50 MHz when using the internal oscillator with a voltage range of 2.4 V to 3.6 V and a temperature range of -40°C to 85°C.
• How do I configure the pin multiplexing to use the desired peripherals?
  The pin multiplexing on the LPC1102LVUKZ can be configured using the PINSELx registers. Each peripheral function has a corresponding PINSELx register that determines which pins are used for that function. The datasheet provides a detailed description of the pin multiplexing options and the corresponding register settings.
• What is the minimum voltage required for the LPC1102LVUKZ to operate?
  The minimum voltage required for the LPC1102LVUKZ to operate is 1.8 V. However, the device can operate down to 1.65 V with reduced performance and functionality.
• How do I use the ADC on the LPC1102LVUKZ?
  The ADC on the LPC1102LVUKZ is a 10-bit successive approximation ADC. To use the ADC, you need to configure the ADC clock, select the ADC channel, and start the ADC conversion. The datasheet provides a detailed description of the ADC registers and the conversion process.
• 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 on the LPC1102LVUKZ is 4 mA. However, the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
