Summary

Provides access to external EEPROM memory over the SPI interface.

Description

The **EEPROM (SPI)** component enables communication with SPI-based EEPROM chips for non-volatile data storage. It can be used to save and retrieve configuration data, logs, calibration parameters, or other persistent values that must be retained even after power cycles.

This component supports a variety of **data element types**, making it flexible for different storage applications.
