+
+You can emulate the nRF54L05 and nRF54L10 targets on an nRF54L15 device using the following snippets:
+
+.. list-table::
+   :header-rows: 1
+
+   * - Functionality
+     - Snippet name
+     - Compatible board targets
+   * - :ref:`emulated-nrf54l05`
+     - ``emulated-nrf54l05``
+     - ``nrf54l15dk/nrf54l15/cpuapp``, ``nrf54l15dk/nrf54l15/cpuapp/ns``
+   * - :ref:`emulated-nrf54l10`
+     - ``emulated-nrf54l10``
+     - ``nrf54l15dk/nrf54l15/cpuapp``, ``nrf54l15dk/nrf54l15/cpuapp/ns``
+
+.. important::
+   You cannot use these snippets with the FLPR core because all memory, including RAM and RRAM, is allocated to the application core.
+
+Currently, using the snippets is supported only on the :ref:`zephyr:nrf54l15dk_nrf54l15` board.

+nRF54L05 snippet
+****************
+
+The ``emulated-nrf54l05`` snippet emulates the nRF54L05 target on an nRF54L15 device.
+
+You have the following options to add the ``emulated-nrf54l05`` snippet to the :term:`build configuration`:
+
+.. tabs::
+
+   .. group-tab:: west
+
+      When building with west, use the following command pattern, where *board_target* corresponds to your board target and `<image_name>` to your application image name:
+
+      .. parsed-literal::
+         :class: highlight
+
+         west build --board *board_target* -- -D<image_name>_SNIPPET="emulated-nrf54l05"
+
+   .. group-tab:: CMake
+
+      When building with CMake, add the following command to the CMake arguments:
+
+      .. code-block:: console
+
+         -D<image_name>_SNIPPET="emulated-nrf54l05" [...]
+
+      To build with the |nRFVSC|, specify ``-D<image_name>_SNIPPET="emulated-nrf54l05" [...]`` in the **Extra CMake arguments** field.
+
+      See :ref:`cmake_options` for more details.
