Other Parts Discussed in Thread: WL1801MOD, BL6450

Hi Champs!

We want to operate both  BL6450 , and WL1801MOD in 1.8V I/O domain . could you please let us know the maximum current required for VDD(3.3V) and VDDIO(1.8V) for both Bluetooth and combo module.

Can you please clarify?

Best Regards

Feroz

    Hi Feroz,

    You should be able to find this information in the datasheet.

    Regards,

    Thanks Gigi!

    However I am not 100% sure if the VDD can be operated at 3.3V and VDD-IO at 1.8V....is the setting even for the tables...

    Would section "WLAN Currents" be the right data for this?
