RF4432X1 Typical Application Circuit

 

Pin Configuration:

RF4432X1 Pin Definition

 

Pin NO. Pin Name Description
1 ANT Connect with 50 ohm coaxial antenna
2 GND Power ground
3 RX_ANT Transmit antenna switch control pin
4 TX_ANT Receiving antenna switch control pin
5 VCC Connect to the positive power supply 3.3V
6 GPIO0 Connect directly to the GPIO0 pin of the chip
7 GPIO1 Connect directly to the GPIO1 pin of the chi
8 GPIO2 Connect directly to the GPIO 2 pin of the chi
9 GND Power ground
10 SDO 0~VDD V digital output, provides serial readback function to internal control register
11 SDI Serial data input. 0~VDD V digital input. This pin is a 4-wire serial data serial data stream bus.
12 SCLK Serial clock input. 0~VDD V digital input. This pin provides a 4-wire serial data clock function.
13 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.
14 nIRQ Interrupt output pin
15 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.
16 GND Power ground
