Typical Circuit
Note:
1．
IRQ is a Interrupt Pin, which can be used to activate SCM to achieve quick
response.IRQ could be unconnected to obtain interruption status by SPI(It' not
recommended because of the low efficiency. And it will influence Power
Consumption.)
2． CE can be connect to high voltage level for a long term， in this way write register must be
set to POWER DOWN mode first.
3．
Truth-value table for relationship between TX_EN and RX_EN as shown:
Driver Statement
1． IC CC2500+RFX2401 is adopted in this module, it's driving means is same as
CC2500, user can operate RF7 in accordance with manual for chip CC2500.
2． Connect LNA EN to MCU, LNA=1(Opened), LNA=0(Closed)
3． If user want to achieve auto-answer, LNA should be in high level during transmit
process, to ensure interface circuit be in working state.
