description DEMO-CR95HF-A 2/5 doc id 018756 rev 3 description the DEMO-CR95HF-A is a demonstration kit which allows to evaluate the performances of st cr95hf 13.56 mhz multiprotocol contactles s transceiver. it incl udes 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. at the end of the initialization, the DEMO-CR95HF-A launches a tag tracking operation. when an rfid or nfc tag is id entified, the led is turned on. figure 1. functional block diagram 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. ! ) # 2 ( & 3 4 - & # " * 4 !

DEMO-CR95HF-A hardware configuration doc id 018756 rev 3 3/5 hardware configuration the DEMO-CR95HF-A demonstration board can use either the uart or the spi as external serial interface. two solder bridges, ssi0 and ssi1, allow choosing the serial interface (see ta bl e 1 ). the spi or uart is then automatically enabled by the cr95hf at power-on. figure 2 shows the board configured to use the spi interface (default configuration). figure 2.
