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

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.

3.2 Eval-ST95HF board powering and Startup
The EVAL-ST95HF board is powered by the USB bus via a Type A / mini B USB cable
connected to a PC.
When powered up, the ST95HF starts the firmware already downloaded in STM32 flash
memory. A general menu appears in which you can reach in various function of the
ST95HF: user can choose mainly between two modes, namely Card emulation mode or
NFC reader mode.
A push button is placed in order to choose the ST95HF LCD screen picture orientation
according to the board direction or in case of two ST95HF used “face to face”.

detail.
3.3 Program/debug the RF transceiver demo board.
In order to flash or debug an STM32 microcontroller application on the EVAL-ST95HF
board, simply connect the 20-pin JTAG/SWD flat ribbon of the STLINK/V2 in-circuit
debugger and programmer to the RF transceiver demonstration board JTAG connector (J3),
then launch STLink.
