Pin Definition

Pin No. Pin Definition Description
1 GND Ground
2 GPIO0 Transmit control pin in internal connected module
3 GPIO1 Receive control pin in internal connected module
4 GPIO2 Connect the GPIO2 pin of the chip
5 VCC Power supply: +3.3V
6 SDO 0–VDD V digital output that provides a serial readback function of the internal control registers
7 SDI Serial Data input. 0–VDD V digital input. This pin provides the serial data stream for the 4-line serial data bus.
8 SCLK Serial Clock input.0–VDD V digital input.This pin provides the serial data clock function for the 4-line serial data bus. Data is clocked into the Si4430/31/32 on positive edge transitions. 
9 nSel Serial Interface Select input. 0– VDD V digital input.This pin provides the Select/Enable function for the 4-line serial data bus. The signal is also used to signify burst read/write mode.
10 nIRQ General Microcontroller Interrupt Status output
11 SDN Shutdown input pin.0–VDD V digital input.SDN should be = 0 in all modes except Shutdown mode.When SDN =1 the chip will be completely shutdown and the contents of the registers will be lost.
12 GND Ground
13 ANT Extra antenna or TR switch control to be used if more GPIO are required. Pin is a hardwired version of GPIO setting 11000, Antenna 2 and can be manually controlled by the antdiv[2:0] bits in register 08h.
14 GND Ground
