nRF52832 Internal oscillators

[Udhayakumar Mahendiran]

Hi,

In nRF52832 datasheet I found that it is having internal oscillators, like 32.768Khz RC oscillator and 64MHz RC oscillator. If it is having internal oscillators what is the need for external oscillators. can anyone please elaborate when and where internal and external Oscillators has to be used?

Hi

Chapter 19.1 in the product specification states: " The HFXO must be running to use the RADIO, NFC module or the calibration mechanism associated with the 32.768 kHz RC oscillator"
