LIV4F reserved pin 7

LZ75 · ‎2025-08-02

Hello,

I have a design with same pinout and package (as LIV4F) that is working with 3.3V from other vendor.

Pin 7 is used as VCC_IO and it is connected to 3.3V.

The question is, can I replace and put the LIV4F instead?

What will happen if pin 7 will get 3.3V (instead of being not connected)?

Any chance of harm or malfunction?

I don't expect logic issue since I'm working with 3.3V anyway (and no conflict with past pin configuration that was VCC_IO)

Hi,

In LIV4F, pin 7 - reserved is not connected inside the module, therefore providing a voltage of 3.3V to this reserved pin will not cause any problems.
