Description. STMicroelectronics EVAL-ST95HF
STMicroelectronics EVAL-ST95HF is an evaluation board with in-built ST95HF multi-protocol contactless transceiver, a microcontroller with 1 MB flash memory, a 2.4-inch LCD screen with 320x200 pixel resolution, and a 47x34mm inductive etched antenna for 13.56 MHz operation. The board is powered by USB and communicates with the transceiver via an SPI bus. EVAL-ST95HF supports ISO/IEC 14443 Type A and B communication, ISO/IEC 15693, ISO/IEC 18092 protocols in Reader mode, and ISO/IEC 14443 Type A in Card Emulations mode. It also supports NFC Forum Type 1, 2, 3, and 4 tags.

Description
The EVAL-ST95HF board includes a ST95HF transceiver, a four turns, 47 mm X 34 mm,
13.56 MHz inductive etched antenna ant its associated tunings components, a STM32F103
32-bits microcontroller with 1 Mbyte of Flash memory and a 2.4 inch TFT LCD with
240 x 230 resolution. The functional scheme is shown in
The board is powered by USB cable. An SPI bus allows the microcontroller to communicate with the ST95HF and then LCD screen.
A four 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 on the EVAL-ST95HF board and boot on it.
