Description

.. code-block:: none

   Zephyr Emulated EEPROM device

Properties
**********

.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``size``
           - ``int``
           - .. code-block:: none

                Total EEPROM size in bytes


             This property is **required**.

         * - ``pagesize``
           - ``int``
           - .. code-block:: none

                Size of a page used to emulate EEPROM in flash


             This property is **required**.

         * - ``partition``
           - ``phandle``
           - .. code-block:: none

                Flash partition used to store the emulated EEPROM data


             This property is **required**.

         * - ``rambuf``
           - ``boolean``
           - .. code-block:: none

                Enable a ram buffer of EEPROM size for improved read speed


         * - ``partition-erase``
           - ``boolean``
           - .. code-block:: none

                Delay erase until complete partition is used. This enables a ram buffer to allow data to be copied during the partition erase. If power is lost during the partition erase the data will be lost.


         * - ``read-only``
           - ``boolean``
           - .. code-block:: none

                Disable writes to the EEPROM




   .. group-tab:: Deprecated node specific properties

      Deprecated properties not inherited from the base binding file.

      (None)

   .. group-tab:: Base properties

      Properties inherited from the base binding file, which defines
      common properties that may be set on many nodes. Not all of these
      may apply to the "zephyr,emu-eeprom" compatible.
