CC1101RGPT from Texas Instruments, in a QFN-20-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial configuration interface clock input |
| 2 | SO (GDO1) | output | Serial configuration interface data output; functions as optional general output pin when CSn is high |
| 3 | GDO2 | output | Digital output pin for test signals, FIFO status signals, clear channel indicator, clock output down-divided from XOSC, or serial output RX data |
| 4 | DVDD | power_in | 1.8 - 3.6 V digital power supply for digital I/O 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 and cannot supply external devices |
| 6 | GDO0 (ATEST) | bidirectional | Digital I/O for test signals, FIFO status signals, clear channel indicator, clock output down-divided from XOSC, serial output RX data, serial input TX data; also analog test I/O for prototype/production testing |
| 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 input signal to LNA in receive mode or positive RF output signal from PA in transmit mode |
| 13 | RF_N | bidirectional | Negative RF input signal to LNA in receive mode or negative RF output signal from PA in transmit 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 reference current |
| 18 | DGUARD | power_in | Power supply connection for digital noise isolation |
| 19 | GND | power_in | Ground connection for digital noise isolation |
| 20 | SI | input | Serial configuration interface data input |
| 21 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
