AFE881H1: Can you use I2C communication to communicate with the AFE881H1 on the UART inputs?

Part Number: AFE881H1


So far, after placing this component on our PCB, we are drawing 100 mA more than its current draw. Is this component usable when connected to I2C? When this component is placed on the board, all other components on the same line have conflicts communicating over I2C. 

Can we use I2C communication to communicate with the AFE881H1 on the UART inputs?

I would greatly appreciate any help using this component.

    Robb, 

    I2C and UART are not compatible communication protocols. I2C is latched based on a serial clock and uses pull up resistors on the two communication lines. UART is sent based on timed bit transmissions and uses driven outputs.

    If you’ve wired the UART lines to I2C, there will definitely be conflicts in communication.
