nRF54LM20A High Voltage Mode?

[sasodoma]

Hi,

I know that the nRF54LM20A was just announced but since it has USB support I am considering it as an option to replace the nRF52840 in the future. Looking at the preliminary datasheet, it seems that an important feature is missing though. The nRF52840 has a High Voltage mode that allows it to be powered directly from the USB port to which it is connected, which to me seems like an awesome feature for a USB IC. The 5V compatibility also enables it to be powered directly from a Li-ion battery and still be very power efficient due to the DC-DC converter. The nRF54LM20A appears to not have a High Voltage mode, so I'm wondering if it is already known, what the recommended way of powering the device from USB will be?

Thank you and best regards,
Sašo

Hi

Correct, the nRF54LM20A does not have a VDDH mode, so you will need a regulator of some sort. An nPM1300 for instance can work like a power management unit in this case.
