| 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 the system parameter sector and |
| one for the EEPROM. |
