How to set the XRA1203 chip to low power mode [Copy link]

     When powered separately, according to the manual, the default minimum power consumption setting is used after power-on reset. The data sheet shows that at 3.3V, it is only 5uA, but the actual tested power consumption is 1.3MA. How could this be?

你是按照这种方法测试的吗？
Test 3: All inputs are steady at VCC or GND to minimize standby current. If internal pull-up is enabled, input voltage level
should be the same as VCC. All GPIOs are configured as inputs. SCL and SDA are at VCC. Outputs are left floating or in
tri-state mode.
