+description: |
+  STMicroelectronics M24LR series are dual-interface (RF + I2C)
+  EEPROM chips. These devices support I2C-based access to both
+  memory and a system area that controls authentication and configuration.
+  They expose two I2C addresses: one for EEPROM memory and one for the
+  system control area (e.g., UID, password management).
