RC7120 replaced by R7620

IoT Modules RC76
1

Hi,

I have a design where I use the RC7120, but due to EOL of it I intend to replace it with RC7620-1.

Everything looks ok (voltage supply, …) BUT the following pins : 30, 32, 37, 39, 111, 113, 125, 128

Are NOT connected in RC7120 (HIZ) but are stated to need to be connected to GND in RC7620-1.

Is it really mandatory ?

For the pin31, RF_DIV on RC7620, can it be left floating ?

Best

you better ask distributor for this kind of question which is something different from specification of RC76
