nRF9280 PDK
Overview
Note
All software for the nRF9280 SiP is experimental and hardware availability is restricted to the participants in the limited sampling program.
The nRF9280 DK is a single-board development kit for evaluation and development on the Nordic nRF9280 System-in-Package (SiP).
The nRF9280 is a multicore SiP with:
an Arm Cortex-M33 core with DSP instructions, FPU, and Armv8-M Security Extensions, running at up to 320 MHz, referred to as the application core
an Arm Cortex-M33 core with DSP instructions, FPU, and Armv8-M Security Extensions, running at up to 256 MHz, referred to as the radio core.
The nrf9280pdk/nrf9280/cpuapp board target provides support for
the application core on the nRF9280 SiP.
The nrf9280pdk/nrf9280/cpurad board target provides support for
the radio core on the nRF9280 SiP.
The nrf9280pdk/nrf9280/cpuppr board target provides support for
the PPR core on the nRF9280 SiP.
nRF9280 SiP provides support for the following devices:
ADC
CLOCK
GPIO
GRTC
I2C
MRAM
PWM
RADIO (Bluetooth Low Energy and 802.15.4)
SPI
UART
USB
WDT
Hardware
nRF9280 DK has two crystal oscillators:
High-frequency 32 MHz crystal oscillator (HFXO)
Low-frequency 32.768 kHz crystal oscillator (LFXO)

Programming and Debugging
Applications for both the nrf9280pdk/nrf9280/cpuapp and
nrf9280pdk/nrf9280/cpurad board targets can be built, flashed,
and debugged in the usual way. See Building an Application
and Run an Application for more details on building and running.
Flashing
As an example, this section shows how to build and flash the Hello World application.
Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing.
To build and program the sample to the nRF9280 DK, complete the following steps:
Connect the nRF9280 DK to your computer using the IMCU USB port on the DK.
Build the sample by running the following command:
# From the root of the zephyr repository west build -b nrf9280pdk/nrf9280/cpuapp samples/hello_world west flash
