nRF54H20 PDK

Overview

Note

All software for the nRF54H20 SoC is experimental and hardware availability is restricted to the participants in the limited sampling program.

The nRF54H20 PDK is a single-board preview development kit for evaluation and development on the Nordic nRF54H20 System-on-Chip (SoC).

The nRF54H20 is a multicore SoC 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 nrf54h20pdk_nrf54h20_cpuapp build target provides support for the application core on the nRF54H20 SoC. The nrf54h20pdk_nrf54h20_cpurad build target provides support for the radio core on the nRF54H20 SoC.

nRF54H20 SoC provides support for the following devices:

  • ADC

  • CLOCK

  • GPIO

  • GPIOTE

  • GRTC

  • I2C

  • MRAM

  • PWM

  • RADIO (Bluetooth Low Energy and 802.15.4)

  • SPI

  • UART

  • USB

  • WDT

Programming and Debugging

Applications for both the nrf54h20pdk_nrf54h20_cpuapp and nrf54h20pdk_nrf54h20_cpurad 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 nRF54H20 PDK, complete the following steps:

First, connect the nRF54H20 PDK to you computer using the IMCU USB port on the PDK. Next, build the sample by running the following command:

# From the root of the zephyr repository
west build -b nrf54h20pdk_nrf54h20_cpuapp samples/hello_world
west flash

Testing the LEDs and buttons in the nRF54H20 PDK

There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr:

You can build and flash the examples to make sure Zephyr is running correctly on your board. The button and LED definitions can be found in boards/arm/nrf54h20pdk_nrf54h20/nrf54h20pdk_nrf54h20_cpuapp.dts.
