Product details
Overview
DEMO-CR95HF-A from STMicroelectronics is a ready-to-use demonstration kit for the CR95HF 13.56 MHz multiprotocol contactless transceiver IC, featuring an integrated STM32F103CB 32-bit microcontroller, a 47 × 34 mm etched inductive antenna, USB-B interface for host PC communication and board powering, and on-board LED indication for RFID/NFC tag detection.
For engineers reviewing the DEMO-CR95HF-A datasheet, DEMO-CR95HF-A pinout, DEMO-CR95HF-A application, or DEMO-CR95HF-A equivalent, this kit supports rapid evaluation of ISO/IEC 15693 and dual-interface EEPROM (M24LR64-R) tag interactions, SPI/UART interface configuration via solder bridges, and USB-powered operation without external supply.
Technical Context
The DEMO-CR95HF-A implements a complete hardware-software evaluation platform centered on the CR95HF transceiver, interfaced to the STM32F103CB MCU via configurable SPI (default) or UART serial link. The board integrates tuning components matched to its 47 × 34 mm planar antenna for optimal 13.56 MHz near-field coupling.
Firmware enables automatic tag discovery and LED activation upon ISO15693 or NFC-compatible tag presence. Host-side software includes dedicated tools for CR95HF register-level control and M24LRxx dual-interface memory management, supporting both contactless and I²C access modes.

FAQ
Is DEMO-CR95HF-A still in active production?
No - DEMO-CR95HF-A is marked as Obsolete in ST's official documentation (Doc ID 018756 Rev 3, September 2012). It remains available through authorized legacy distributors and Aetrix Electronics' inventory for design continuity and legacy system support, but no new revisions or firmware updates are issued.
Can the CR95HF transceiver be replaced with a newer ST transceiver on this board?
No - the DEMO-CR95HF-A PCB is specifically laid out for the CR95HF QFN32 package and its associated matching network. Pinout, power sequencing, and antenna coupling are not compatible with successors like the ST25R3916 or ST25DV series without hardware redesign.
What software tools are required to operate the demo kit?
The kit requires ST's CR95HF Development Software (for transceiver register control and protocol testing) and M24LRxx Application Software (for dual-interface EEPROM read/write over I²C and RF). Both are archived on st.com and compatible with Windows 7/10; no additional drivers beyond standard USB CDC are needed.
Does the board support NFC Forum Tag Type 4 emulation?
No - while the CR95HF supports ISO/IEC 14443A/B and ISO15693, it lacks native NDEF message formatting and NFC Forum-certified tag type 4 emulation logic. The included firmware enables raw command exchange but does not implement full Tag Type 4 behavior per NFC Forum specifications.
