NRF24L01P-R

Nordic Semicon · RF Transceiver ICs · QFN-20-EP(4x4)

NRF24L01P-R from Nordic Semicon, 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 CE input Chip enable; high activates RX or TX mode (5V tolerant).
2 CSN input SPI chip select input; active low (5V tolerant).
3 SCK input SPI clock input; 0 to 10 Mbps maximum frequency (5V tolerant).
4 MOSI input SPI slave serial data input (5V tolerant).
5 MISO tri_state SPI slave serial data output; tri-state capable, 0 to 10 Mbps.
6 IRQ output Maskable active-low interrupt output; asserted by RX_DR, TX_DS, or MAX_RT events.
7 VDD power_in Power supply input; +1.9 to +3.6 V DC supply range.
8 VSS power_in Ground; 0 V return.
9 XC2 output Crystal oscillator output pin 2; connects to crystal load capacitor.
10 XC1 input Crystal oscillator input pin 1; 16 MHz ±60 ppm crystal reference.
11 VDD_PA power_out Power amplifier regulated supply output; +1.8 V for internal PA.
12 ANT1 bidirectional Balanced RF antenna interface 1 for 2.4 GHz transceiver; typical load impedance 15Ω+j88Ω.
13 ANT2 bidirectional Balanced RF antenna interface 2 for 2.4 GHz transceiver; typical load impedance 15Ω+j88Ω.
14 VSS power_in Ground; 0 V return.
15 VDD power_in Power supply input; +1.9 to +3.6 V DC supply range.
16 IREF input Reference current input; connect 22 kΩ resistor to ground.
17 VSS power_in Ground; 0 V return.
18 VDD power_in Power supply input; +1.9 to +3.6 V DC supply range.
19 DVDD power_out Digital supply output for decoupling; internally regulated voltage.
20 VSS power_in Ground; 0 V return.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
