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 I
2
C 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.
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.
