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

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.

The DATALOG-M24LR-A allows system

designers to start developing a standalone or an

embedded datalogger.

The DATALOG-M24LR-A reference board is

supported by ST DEVKIT-M24LR-A, STARTKIT-

M24LR-A and DEMOKIT-M24LR-A evaluation

kits, for which a demonstration software is

available.

The reference board Gerber files can be

downloaded from http://www.st.com.
