CC1101RGPR

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

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).
