3.6 OTP Programming - OTPVDD supply voltage (external power supply)

[WojciechS]

Hello All,

Regarding technical specification,

In order to coordinate the OTPVDD supply voltage with read and write operations, it is
recommended driving this supply from the POWERIOVDD output pin on nRF7002. This also ensures there
will be no leakage associated with the OTP across sleep cycles, where the digital supply rail is removed.

Q: Are there any situations when external OTPVDD supply voltage is required?

Thank you.

Hello,

PWRIOVDD is an internally generated supply, used for supplying OTPVDD through an external connection. It cannot be used for anything else. This supply is automatically controlled in the device.
