description:
13
  STMicroelectronics M24LR series are dual-interface (RF + I2C)
14
  EEPROM chips. These devices support I2C-based access to both
15
  memory and a system area that controls authentication and configuration.
16
  They expose two I2C addresses, one for the system parameter sector and
17
  one for the EEPROM.
