CC1101RGPT

Texas Instruments · RF Transceiver ICs · QFN-20-EP(4x4)

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).
