Description EVAL-RX95HF
2/4 DocID025301 Rev 1
Description
The EVAL-RX95HF is an evaluation kit for RX95HF NFC transceiver. This component is a
13.56 MHz near field communication transceiver for tag emulation and could be used with
an NFC Reader (NFC smartphone, CR95HF) to exchange NDEF messages (URI, VCARD,
URL) or establish a Proprietary Data exchange protocol communication. The
communication protocol is based on ISO/IEC 14443 Type A.
The EVAL-RX95HF is powered through the USB bus. It includes an RX95HF transceiver for
tag emulation, a 47 x 34 mm 13.56 MHz inductive etched antenna and its associated tuning
components. The RX95HF communicates with the STM32F103RF 32-bit MCU via the SPI
bus.
