M24LR64-R datalogger hardware

The M24LR64-R datalogger hardware is implemented using the following components:

●

Dual Interface EEPROM (M24LR64-R)

●

8-bit microcontroller (STM8L)

●

Temperature sensor (STTS75)

●

RF antenna, size : 75 mm x 45 mm (2.9 in x 1.77 in)

Refer to Figure 1.

Compatible RF readers

The M24LR64-R data logger reference design is able to work with following readers :

●

Development kit reader (DEVKIT-M24LR-A): mid-range RF reader (ISO 15693, RF

13.56 MHz) interfaced via the USB bus (ref: FEIG ID ISC.MR10 A) connected to an

external pad antenna (FEIG ID ISC.ANT340/240) and an external power supply for

increased read range. See Figure 2

●

Demonstration kit reader (DEMOKIT-M24LR-A): mid-range RF reader (ISO 15693,

RF 13.56 MHz) interfaced via the USB bus (ref: FEIG ID ISC.MR101 USB). See

Figure 3

●

Starter kit Reader (STARTERKIT-M24LR-A): mid-range RF reader (ISO 15693, RF

13.56 MHz) interfaced via the USB bus. See Figure 4.

Note:

The serial EEPROM USB reader is not suitable for use with the M24LR64-R datalogger.
