关于这个芯片-SL3S1003FUD，是否可以设计成用继电器短接或断开OUT-VDD，开启或者关闭芯片射频功能？
如果不行的话，请问有哪个型号的RFID芯片可以实现这个功能？在900M频段的。
谢谢各位。

Regarding this chip-SL3S1003FUD, can it be designed to short-circuit or disconnect OUT-VDD with a relay to turn on or off the chip's radio frequency function?
If not, which model of RFID chip can achieve this function? In the 900M band.
Thank you all.
Hi 李烨，
这两个引脚不是用来开启或者关闭芯片射频功能的，是用来实现tamper alarm功能的，具体参考下图：
其他产品好像没有能满足你这个需求的，如果你要实现开启或者关闭芯片射频功能，只能通过连通或断开天线和tag之间的连接来实现。
Have a great day,

Hi ,
我想你可以看一下UCODE I2C这款芯片，你可以通过单片机连接I2C来控制射频端的开关。
