Description
Shutdown Input Pin .
1
SDN
I
0–VDD V digital input. SDN should be = 0 in all modes except Shutdown mode.
When SDN = 1, the chip will be completely shut down, and the contents of the
registers will be lost.

I
Differential RF Input Pins of the LNA.
See application schematic for example matching network.
Transmit Output Pin.

O
The PA output is an open-drain connection, so the L-C match must supply
VDD (+3.3 VDC nominal) to this pin.
5
NC
No Connect. Not connected internally to any circuitry.

+1.8 to +3.6 V Supply Voltage Input to Internal Regulators.
The recommended VDD supply voltage is +3.3 V.
Programmable Bias Output with Ramp Capability for External FET PA.
See "5.4. Transmitter (TX)" on page 34.
+1.8 to +3.6 V Supply Voltage Input to Internal Regulators.
The recommended VDD supply voltage is +3.3 V.
General Purpose Digital I/O.
May be configured through the registers to perform various functions including:

GPIO1
I/O
Microcontroller Clock Output, FIFO status, POR, Wake-Up timer, Low Battery
Detect, TRSW, AntDiversity control, etc.
General Microcontroller Interrupt Status Output.
When the Si4463/61 exhibits any one of the interrupt events, the nIRQ pin will

be set low = 0. The Microcontroller can then determine the state of the inter-
rupt by reading the interrupt status. No external resistor pull-up is required, but
it may be desirable if multiple interrupt lines are connected.
