Removed the external 32MHz oscillator on nrf52810

[Wiloui]

Hi,

We want to use the NRF52810 without radio and we don't want to put the external oscillator to reduce the PCB size 

I would like to know if necessary to have the external 32 MHz oscillator if don't use the radio ?

All peripheral can work with HFINT ?

best regards

Hi,

 

There are a couple of modules that need the 32 MHz crystal:

• Radio
• NFC (not relevant for nRF52810)
• LFRC calibration
• USBD (not relevant for nRF52810)
• SAADC for improved accuracy
• UART for improved accuracy, requirement depending on external counterpart and baudrate
• TEMP

 

Best regards,

Andreas

Tanks for the answer,

In first time we are going to keep the oscillator and we will test it if can removed.

Hi,

 

That is probably a wise approach.
