Application note
CR95HF library for ISO15693
and Dual Interface EEPROM products
Introduction
This document describes the CR95HF library which allows a microcontroller to drive the
CR95HF 13.56 MHz multiprotocol contactless transceiver using an SPI or UART interface in
order to perform ISO15693 wireless communications with Dual Interface EEPROM devices.
The library was developed to speed up the development of applications using the CR95HF
in conjunction with a contactless tag based on an M24LRXX dual interface EEPROM.
The CR95HF library is split into three layers:
■ Low level CR95HF layer
■ Standard ISO15693 protocol layer
■ Dual Interface EEPROM specific layer
The library code has been developed in ANSI C language, and validated on an STM32
microcontroller.
