General Description：
The MC38214 is a highly integrated RF front-end for 802.15.4,ZigBee Thread,Bluetooth Smart,Bluetooth Audio and systems in the proprietary ISM wireless 2.4GHz band.
In the unique Auto-Tx mode,the device can automatically switch from Rx to Tx mode when the input power of the Tx/Rx port exceeds-12dBm.
When the Auto pin Pin7 level is pulled high, the Auto-Tx function is turned on and the chip will automatically switch between Tx and Rx(or Bypass) modes based on the input power of Tx/Rx pin4(-12dBm threshold),eliminating the need for TxEn and RxEn to be connected to the SoC for timing control.

General Description：
The MC31218 is a compact,highly integrated RF front-end for systems in the 802.15.4,ZigBee,
Thread,ANT+,Bluetooth Smart, and proprietary ISM wireless 2.4 GHz bands. The easy-to-use
MC2IC provides PA,Bypass functionality,and compact Tx/Rx switching.It requires only a single
battery supply voltage and a single logic control signal.
Ø Ultra-low bypass(=off) current；
Ø Low TX current（24mA @12dBm)；
Ø DFN-8 package,small size,low cost；
Ø 1-Bit control between bypass and PA modes。
