Application note
CR95HF library for ISO/IEC 14443-3 and SRIX contactless tag ICs
1
Introduction
This document describes the ISO/IEC 14443-3 libraries used by a microcontroller to drive
the CR95HF 13.56 MHz multiprotocol contactless transceiver using an SPI or UART
interface in order to perform wireless communications with ISO/IEC 14443 Type A or B
contactless tag.
The library was developed to speed up the development of applications using the CR95HF.
The CR95HF library is composed of three layers:
■ CR95HF low level layer
■ Standard ISO/IEC 14443-3 protocol layer (type A and type B)
■ SRIX4K product specific layer
The library code has been developed in ANSI C language, and validated on an STM32
evaluation board.
