Communication interfaces

The communications between the STM8L101K3, M24LR64-R, and STTS75 are performed

through an I2C bus. The STM8L101K3 acts as the I2C master, and both the M24LR64-R

and STTS75 act as slaves. The Dual interface EEPROM is also connected to an antenna to

communicate with the RFID reader. Refer to Figure 3 for an overview of the communication

interfaces.

Power management

The datalogger is a low power application requiring a particular power management. The

entire power supply is managed by the microcontroller which is the only device directly
