1.1

M24LRXX dual interface EEPROM

The M24LRXX is a dual interface EEPROM which can be accessed either through an I2C

serial bus or a contactless interface using the ISO 15693 RFID protocol.

To easily access the M24LRXX content through its RF interface, ST offers several evaluation

kits, among which are the DEMOKIT-M24LR-A and the DEVKIT-M24LR-A.

Refer to the product datasheet and to application note AN3163 “Configuring your ISO 15693

reader to support the M24LRXX” for more in-depth information on the M24LRXX and for

explanations on the RF and I2C communication protocols. Both documents are available

from http://www.st.com.

PR101-USB and MR101-USB FEIG contactless readers

1.2.1

PR101-USB FEIG reader

The PR101-USB RF reader is delivered within ST DEMOKIT-M24LR-A. It supports the

ISO 15693 protocol with high datarate transfers and one subcarrier to communicate with

M24LRXX-based transponders by sending RF ISO 15693 commands. The reader is

connected to the host-computer USB port (see Figure 2).
