Application note
Storing data into the NDEF memory of M24SR
Introduction
M24SRxx-Y is a family of dynamic NFC Forum Type 4 Tags, based on ISO/IEC 14443 Type
A technology:
- Dynamic tag: EEPROM area can be accessed either from I²C or RF interface
- NFC Forum Type 4 Tag: memory organization and access complies with the
associated NFC Forum specification
The purpose of this application note is to give some guidelines on how to access and
organize the memory of M24SRxx-Y products, as per the NFC Forum standards and
M24SRxx-Y specificities.
This document specifically proposes some mechanisms to store proprietary data, with or
without standard NFC data (NDEF).
