Product details
Overview
DATALOG-M24LR-A from STMicroelectronics is a ready-to-use reference board for standalone or embedded datalogging, integrating the M24LR64-R Dual Interface EEPROM, STM8L101K3 8-bit microcontroller, STTS75 temperature sensor, 13.56 MHz etched antenna (20 mm × 40 mm), and CR2330 coin cell battery. It enables RFID-based temperature data logging via I²C and ISO 15693 RF interface.
For engineers reviewing the DATALOG-M24LR-A datasheet, DATALOG-M24LR-A pinout, DATALOG-M24LR-A application, or DATALOG-M24LR-A equivalent, key considerations include its dual-interface EEPROM integration, on-board temperature sensing capability, SWIM programming support, and compatibility with ST's DEVKIT-M24LR-A, STARTKIT-M24LR-A, and DEMOKIT-M24LR-A evaluation ecosystems.
Technical Context
The board implements a complete RFID-enabled datalogger architecture: the STM8L101K3 MCU executes firmware to acquire temperature readings from the STTS75 sensor and store them in the M24LR64-R EEPROM via I²C; the same EEPROM exposes stored data over 13.56 MHz ISO 15693 RF link without MCU intervention.
It supports both contact (I²C) and contactless (RF) access to logged data, enabling low-power, battery-operated operation with wake-up-on-field capability - critical for maintenance-free environmental monitoring deployments.

FAQ
Does DATALOG-M24LR-A support firmware updates?
Yes - it features a SWIM (Single Wire Interface Module) connector for in-circuit programming and firmware upgrades of the STM8L101K3 microcontroller. The preloaded firmware handles temperature sampling and EEPROM storage, but users can reprogram it using ST's STVP or STM8CubeIDE tools with standard SWIM adapters.
Can the M24LR64-R EEPROM be accessed without powering the microcontroller?
Yes - the M24LR64-R operates independently in RF mode: when an ISO 15693 reader energizes the on-board antenna, the EEPROM responds directly over RF without requiring the STM8L101K3 to be powered or active, enabling true zero-power data retrieval.
What software tools are provided for DATALOG-M24LR-A?
ST provides the M24LR64-R_Datalogger_application_software (PC application) for configuration, real-time temperature display, and data download, plus full firmware source code and Gerber files - all available for download from www.st.com under Doc ID 17870.
Is the DATALOG-M24LR-A still in active production?
No - per STMicroelectronics' official documentation (Doc ID 17870 Rev 2), DATALOG-M24LR-A is marked "Obsolete Product(s)" as of the October 2010 revision. It remains available for legacy design support and educational use, but no new silicon or board revisions are planned.
