在LAUNCHPAD CC1310使用rtos standbyPin测试出来是9uA,但是手册上standby应该是0.7uA,有什么地方需要注意的吗?还是我对0.7uA功耗理解有误?
Susan Yang:
您是使用下面的例程测试的?

This example will cycle the device between active and standby states. The CPU will toggle the LEDs each time it wakes up from standby, using the PIN driver, and then immediately return to standby.
另外需要注意
Note that in order to get lowest standby current, the JTAG pins TMS and TCK should be disconnected after programming the device by removing the jumpers on P408 of the SmartRF06 EB. TMS and TCK have internal pull-ups and are driven low when inactive from the emulator, hence after programming the device these jumpers should be removed to avoid the extra leakage current.
为了获得最低的待机电流,在对器件进行编程之后,应通过移除SmartRF06 EB的P408上的跳线来断开JTAG引脚TMS和TCK的连接。 TMS和TCK具有内部上拉电路,当从仿真器处于非活动状态时,它们被驱动为低电平,因此,在对器件进行编程之后,应将这些跳线移除,以避免产生额外的泄漏电流。
