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.
