Description
The DEMO-CR95HF-A is a demonstration kit which allows to evaluate the performances of
ST CR95HF 13.56 MHz multiprotocol contactless transceiver. It includes a ready-to-use
board to interface with the CR95HF host PC demonstration software through an USB
interface.
The DEMO-CR95HF-A is powered through the USB bus and no external power supply is
required. It includes a CR95HF contactless transceiver, a 47 x 34 mm 13.56 MHz inductive
etched antenna and its associated tuning components.
By default, the CR95HF communicates with the STM32F103CB 32-bit MCU via the SPI
bus. The interface can then be changed to UART.

The DEMO-CR95HF-A is delivered with the following firmware and software which can be
downloaded from http://www.st.com:
● STM32 DEMO-CR95HF-A-application-firmware: on-board demonstration firmware
allowing the CR95HF and the host PC to communicate through the USB bus
● M24LRxx_application_software: a PC software that manages the communications with
the ISO15693 and Dual Interface EEPROM tags.
