Other Parts Discussed in Thread: CC2530

The lowest current of my zigbee module is almost 100uA when it inters standby mode 2.We use CC2530 as the tranceiver and MCU.My circuit is the same as the reference design.The datasheet says the current of CC2530 should be almost 1uA.Why the difference is so big?I need you help for this.Thanks a lot!

Make sure all of your unused port IO pins are configured properly. If you aren't using a port pin and it is not connected to anything then you should configure it as an output and set it high or low. Unconnected pins should never be configured as input tristate. A connected input pin that is pulled up or down will draw current if it is being driven opposite to the pull.
