Developing your M24LR64-R datalogger application for temperature acquisition

Keywords:M24LR64-R datalogger? temperature acquisition? EEPROM?

The M24LR64-R is a dual interface EEPROM. Since it has both a 13.56MHz ISO 15693 RFID and a 400kHz I2C interface, the device is a good solution for RF-enabled sensors for which ST has developed a reference design. One of the main benefits brought by the M24LR64-R is that the sensor data can be accessed in read and write mode without consuming any on-board power.

This application note presents a practical useful application for the M24LR64-R datalogger. It describes an autonomous battery-powered datalogger able to record and store 64Kbits of temperature data using the M24LR64-R dual interface EEPROM (I2C and RF). The datalogger microcontroller is an STM8L101K3. It communicates with the M24LR64-R using its serial interface and controls an STTS75 digital temperature sensor.
