SI4463 Pin Configuration
| Pin | Pin Name | I/0 | Description |
|---|---|---|---|
| 1 | SDN | I | 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 shut down, and the contents of the registers will be lost. |
| 2 | RXp | I | Differential RF Input Pins of the LNA. See application schematic for example matching network. |
| 3 | RXn | I | Differential RF Input Pins of the LNA. See application schematic for example matching network. |
| 4 | TX | O | Transmit Output Pin. 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 | It is recommended to connect this pin to GND per the reference design sche- matic. Not connected internally to any circuitry. | |
| 6 | VDD | VDD | +1.8 to +3.8 V Supply Voltage Input to Internal Regulators. The recommended VDD supply voltage is +3.3 V. |
| 7 | TXRAMP | O | Programmable Bias Output with Ramp Capability for External FET PA. See "5.4. Transmitter (TX)" on page 33. |
| 8 | VDD | VDD | +1.8 to +3.8 V Supply Voltage Input to Internal Regulators. The recommended VDD supply voltage is +3.3 V. |
| 9 | GPIO0 | I/O | General Purpose Digital I/O. |
| 10 | GPIO1 | I/O | May be configured through the registers to perform various functions including: Microcontroller Clock Output, FIFO status, POR, Wake-Up timer, Low Battery Detect, TRSW, AntDiversity control, etc. |
| 11 | nIRQ | O | 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. |
| Pin | Pin Name | I/0 | Description |
| 12 | SCLK | I | 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 Si4463/61 on positive edge tran- sitions. |
| 13 | SDO | O | 0-VDD V Digital Output. Provides a serial readback function of the internal control registers. |
| 14 | SDI | I | Serial Data Input. 0-VDD V digital input. This pin provides the serial data stream for the 4-line serial data bus. |
| 15 | nSEL | I | Serial Interface Select Input. 0-VDD V digital input. This pin provides the Select/Enable function for the 4-line serial data bus. |
| 16 | XOUT | O | Crystal Oscillator Output. Connect to an external 25 to 32 MHz crystal, or leave floating when driving with an external source on XIN. |
| 17 | XIN | I | Crystal Oscillator Input. Connect to an external 25 to 32 MHz crystal, or connect to an external source. |
| 18 | GND | GND | When using an XTAL, leave floating per the reference design schematic. When using a TCXO, connect to TCXO GND, which should be separate from the board's reference ground plane. |
| 19 | GPIO2 | I/O | General Purpose Digital I/O. |
| 20 | GPIO3 | I/O | May be configured through the registers to perform various functions, including Microcontroller Clock Output, FIFO status, POR, Wake-Up timer, Low Battery Detect, TRSW, AntDiversity control, etc. |
| PKG | PADDLE_GND | GND | The exposed metal paddle on the bottom of the Si446x supplies the RF and cir- cuit ground(s) for the entire chip. It is very important that a good solder connec- tion is made between this exposed metal paddle and the ground plane of the PCB underlying the Si446x. |
