Part Number: AM2732

Hi Experts

Could you pls help check what‘s the leakage current of GPIO when GPIo and pinmux is configured in high impedance state?

Thanks

Ken

    Hi Ken,

    Apologies for the lack of reply here, I am currently out of office but I will be back and will look into this for you on 12/5.

    Hello Ken,

    The GPIO when in high impedance state (receiver disabled, pull disabled) as a leakage current minimum of -18 uA and a leakage current maximum of 18 uA.

    Here is a full table of leakage currents for the GPIO which will be added into the datasheet in the future:

    Parameter Min Typ Max Unit
    Input Leakage Current, Receiver Disabled, Pull Disabled -18 18 uA
    Input Leakage Current, Receiver Disabled, Pullup Enabled -243 -100 -19 uA
    Input Leakage Current, Receiver Disabled, Pulldown Enabled 51 100 210 uA

    Best Regards,
