Typical Application Circuit of RF transceiver module RF4432

Pins of RF transceiver module RF4432

 

Pin NO. Pin Name Description
1 GND Power ground
2 GPIO0 The control pin of the transmitter switch is connected inside the module
3 GPIO1 The control pin of the transmitter switch is connected inside the module
4 GPIO2 Connect directly to the GPIO2 pin of the chip
5 VCC Positive power supply 3.3V
6 SDO 0~VDD V digital output, provides serial readback function to internal control register.
7 SDI Serial data input. 0~VDD V digital input. This pin is a 4-wire serial data serial data stream bus.
8 SCLK Serial clock input. 0~VDD V digital input. This pin provides a 4-wire serial data clock function.
9 nSEL Serial interface select input pin. 0~VDD V digital input. This pin provides select/enable function for 4-wire serial data bus. This signal is also used to indicate burst read/write mode.
10 nIRQ Interrupt output
11 SDN Chip enable pin. 0~VDD V digital input. SDN=0 in all modes except shutdown mode. When SDN=1, the chip will be completely shut down and the contents of the register will be lost.
