Pin Definition

Pin No. Pin Definition Description
1 VCC Power supply
2 GND Ground
3 NC No Connect
4 NC Connect
5 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.
6 nIRQ General Microcontroller Interrupt Status output
7 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.
8 GND Ground
9 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. 
10 SDI Serial Data input. 0–VDD V digital input. This pin provides the serial data stream for the 4-line serial data bus.
11 SDO 0–VDD V digital output that provides a serial readback function of the internal control registers
12 GPIO2 Test receiver sensitivity 
13 NC No Connect
14 NC No Connect
15 GND Ground
16 ATN 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.
