[求助] XRA1203芯片怎么设置为低功耗模式

    在单独供电的情况下，根据手册说明，上电复位后为默认最低功耗设置，数据手册上3.3V时，只有5uA，而实际测试功耗1.3MA，怎么会这样子！

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.

是的。
