CC1101RGPR from Texas Instruments, in a QFN-20-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial configuration interface clock input. |
| 2 | SO (GDO1) | tri_state | Serial configuration interface data output; default 3-state operation, reconfigurable as general output when CSn high. |
| 3 | GDO2 | output | Configurable digital output for test signals, FIFO status, clear channel indicator, XOSC clock output, or RX data. |
| 4 | DVDD | power_in | 1.8-3.6 V digital power supply for digital I/Os and digital core voltage regulator. |
| 5 | DCOUPL | power_out | 1.6-2.0 V digital power supply output for decoupling; intended for CC1101 use only. |
| 6 | GDO0 (ATEST) | bidirectional | Configurable digital I/O for test signals, FIFO status, clear channel, XOSC clock output, RX data, TX data input, and temperature sensor output. |
| 7 | CSn | input | Serial configuration interface chip select input. |
| 8 | XOSC_Q1 | bidirectional | Crystal oscillator pin 1 or external clock input. |
| 9 | AVDD | power_in | 1.8-3.6 V analog power supply connection. |
| 10 | XOSC_Q2 | bidirectional | Crystal oscillator pin 2. |
| 11 | AVDD | power_in | 1.8-3.6 V analog power supply connection. |
| 12 | RF_P | bidirectional | Positive RF signal: input to low-noise amplifier in RX mode, output from power amplifier in TX mode. |
| 13 | RF_N | bidirectional | Negative RF signal: input to low-noise amplifier in RX mode, output from power amplifier in TX mode. |
| 14 | AVDD | power_in | 1.8-3.6 V analog power supply connection. |
| 15 | AVDD | power_in | 1.8-3.6 V analog power supply connection. |
| 16 | GND | power_in | Analog ground connection. |
| 17 | RBIAS | bidirectional | External bias resistor connection for setting reference current. |
| 18 | DGUARD | power_in | Digital power supply connection for digital noise isolation. |
| 19 | GND | power_in | Digital ground connection for noise isolation. |
| 20 | SI | input | Serial configuration interface data input. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
