DATALOG-M24LR-A

DATALOG-M24LR-A Datalogger reference board for the M24LR64-R Dual Interface EEPROM Data brief Features ■ Ready-to-use printed circuit board (PCB) with: – 20 mm x 40 mm 13.56 MHz inductive antenna etched on the PCB – STM8L101K3 8-bit microcontroller – STTS75 temperature sensor – CR2330 battery – ON/OFF switch – SWIM connector for microcontroller firmware upgrade The DATALOG-M24LR-A allows system designers to start developing a standalone or an embedded datalogger. Description The DATALOG-M24LR-A is a ready-to-use PCB that features an M24LR64-R Dual Interface EEPROM IC connected to an STM8L101K3 8-bit microcontroller through an I2C bus on one side, and to a 20 mm x 40 mm 13.56 MHz etched RF antenna on the other one side. The STM8L101K3 is also interfaced with an STTS75 temperature sensor and a CR2330 coin cell battery. Figure 1. The DATALOG-M24LR-A reference board is supported by ST DEVKIT-M24LR-A, STARTKITM24LR-A and DEMOKIT-M24LR-A evaluation kits, for which a demonstration software is available.
