1. Please disable pull-up resistance
e.g.;
PIN_PULLUP_DIS(PERIPHS_IO_MUX_MTMS_U);

2. It seems the leakage current is from the 3.3v not the IO itself.
If so, that's why the current would be 3.3v/1Mohm = 3.3uA.

We will verify this issue and let you know the result.

Thanks.

According to the datasheet of the esp8266ex (wroom-02) the input leakage current is 50nA.
However after testing with 1MOhm resistors I noticed that the voltage drop across the resistor was way bigger than expected.
A current measurement between Vcc and a gpio pin configured as input reveals that there is a current of 3.6uA.
Could you please check my findings
