Hardware that runs Matter protocol applications must meet specification requirements, including providing the right amount of flash memory and being able to run Bluetooth® LE and Thread or Wi-Fi® concurrently.
Currently the following SoCs from Nordic Semiconductor are supported for use with the Matter protocol:
- :ref:`nRF5340 <programming_board_names>` (Matter over Thread and Matter over Wi-Fi through the
nrf7002ekshield) - :ref:`nRF5340 + nRF7002 <programming_board_names>` (Matter over Thread and Matter over Wi-Fi)
- :ref:`nRF52840 <programming_board_names>` (Matter over Thread)
- :ref:`nRF54L15 <programming_board_names>` (Matter over Thread)
- :ref:`nRF54L10 <programming_board_names>` (Matter over Thread)
SoCs from Nordic Semiconductor that can run the Matter protocol over Thread can also work with external Front-End Modules. For more information about the FEM support in the |NCS|, see :ref:`ug_radio_fem` and :ref:`nRF21540 DK <programming_board_names>`.
For the currently supported SoCs, you must use an external memory with at least 1 MB of flash for nRF52840 and nRF54L10, and 1.5 MB for nRF5340 and nRF54L15. This is required to perform the DFU operation.
Note
The nRF54L15 supports DFU with image compression, which may eliminate the need for external flash. For more details, see :ref:`mcuboot_image_compression`.
The development kits for the supported SoCs from Nordic Semiconductor are supplied with the MX25R64 type of external flash that meets these memory requirements. However, it is possible to configure the SoCs with different QSPI or SPI memory if it is supported by Zephyr. For this purpose, check the reference design for Nordic DKs for information about how to connect the external memory with SoC, specifically whether the pins are designed for the QSPI or the high-speed SPIM operations.
RAM and flash memory requirement values differ depending on the DK and the programmed sample.
The following tables list memory requirement values for Matter samples.
Values are provided in kilobytes (KB).

Note
The results for Link-Time Optimization (LTO) are based on building the Thread library from sources.
If you use the binary Thread library version, the ROM usage may be higher.
The following tabs show how the :ref:`Matter stack architecture in the nRF Connect SDK <ug_matter_overview_architecture_integration_stack>` translates to actual memory maps for each of the available :ref:`ug_matter_overview_architecture_integration_designs`. The memory values match RAM and flash memory requirements listed above.
Each tab shows the memory maps for the development kits supported by the Matter protocol, including two memory maps for the :ref:`matter_weather_station_app`, which uses Nordic Thingy:53.

You can generate :ref:`Partition Manager's ASCII representation <pm_partition_reports>` of these tables by running the following command for your respective board_target:
west build -b board_target -t partition_manager_report
For example, for the nrf7002dk/nrf5340/cpuapp board target, the command is as follows:
west build -b nrf7002dk/nrf5340/cpuapp -t partition_manager_report:ref:`Diagnostic logs support<ug_matter_configuration_diagnostic_logs>` requires changing the RAM memory layout by adding three retained RAM partitions to keep the log data persistent across device reboots. The :ref:`ug_matter_diagnostic_logs_snippet` adds these RAM partitions, and also reduces the amount of SRAM available for the application by the size of the retained partitions. You can adjust the retained partitions for your needs by editing the :ref:`ug_matter_diagnostic_logs_snippet` devicetree file for the relevant board.
The following tabs show the RAM memory layout defined for the default configuration of the :ref:`ug_matter_diagnostic_logs_snippet` for each development kit.
