MKL04Z16VLC4 datasheet by Freescale Semiconductor

MKL04Z16VLC4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the MKL04Z16VLC4?
  The maximum clock frequency of the MKL04Z16VLC4 is 48 MHz, which is the maximum frequency of the internal oscillator.
• How do I configure the MKL04Z16VLC4 to use an external clock source?
  To configure the MKL04Z16VLC4 to use an external clock source, you need to set the EXTAL and XTAL pins as clock inputs, and configure the Clock Management Unit (CMU) to use the external clock source. This is done by setting the CLKOSRC register to 0b10 and configuring the EXTAL and XTAL pins as clock inputs.
• What is the maximum current consumption of the MKL04Z16VLC4?
  The maximum current consumption of the MKL04Z16VLC4 depends on the operating mode and frequency. According to the datasheet, the maximum current consumption is around 10.5 mA at 48 MHz with all peripherals enabled.
• How do I use the ADC on the MKL04Z16VLC4?
  The ADC on the MKL04Z16VLC4 is a 12-bit successive approximation register (SAR) ADC. To use it, you need to configure the ADC module by setting the ADCSC1 and ADCSC2 registers, select the ADC channel, and start the conversion. You can then read the ADC result from the ADCRH and ADCRL registers.
• Can I use the MKL04Z16VLC4 with an external crystal oscillator?
  Yes, the MKL04Z16VLC4 can be used with an external crystal oscillator. The device has an internal oscillator circuit that can be connected to an external crystal oscillator. The external crystal oscillator can be used to generate a clock signal for the device.
