Evaluation board for ST95HF NFC transceiver

Introduction

The EVAL-ST95HF is a ready-to-use development kit used to evaluate functions and
performances of the RF transceiver ST95HF in Reader mode, Card emulation mode or Peer
to Peer Mode for standard contactless applications.

The EVAL-ST95HF kit supports:

• ISO/IEC 14443 Type A and B communication in Reader;

• ISO/IEC 15693 in Reader mode only;

• ISO/IEC 14443 Type A communication in Card emulations mode;

• ISO/IEC 18092 protocols in Reader modes.

The ST95HF also supports the detection, reading and writing of NFC Forum Type 1, 2, 3
and 4 tags.

The EVAL-ST95HF kit includes a ST95HF transceiver, a 4 turns 47 x 34 mm 13.56 MHz
inductive etched antenna and its associated tuning components, a STM32F103 32-bits
microcontroller with 1 Mbyte of Flash memory and a TFT LCD 2.4 inch and 240*230
resolution.

1 Description

The EVAL-ST95HF board includes a ST95HF transceiver, a 4 turns 47 X 34 mm, 13.56 MHz
inductive etched antenna ant its associated tunings components, a STM32F103 32-bits
microcontroller with 1Mbytes of Flash memory and a TFT LCD 2.4 inch and 240*230
resolutions. The functional scheme is shown in Figure 1.

It is powered by USB cable. A SPI bus allows the microcontroller to communicate with the
ST95HF and LCD screen.

A 4 positions joystick is used to move in the menu.

Two other pushbuttons are placed on the board, one for the reset, the second to rotate the
LCD picture.

The download is possible through the JTAG connector.

The ST android application "ST95HF demo App" shows a proprietary IAP application. The
user can upload from the NFC reader (NFC Phone or RFID reader) the firmware of the
STM32F103 of the EVAL-ST95HF board and boot on it.

More information on the ST95HF evaluation kit and associated demonstration software can
be found at www.st.com.
