STMICROELECTRONICS PLUG-CR95HF-B 子板, CR95HF 13.56MHZ 首发芯片
The is a development board for CR95HF 13.56MHz multi protocol contactless transceiver IC with SPI and UART serial access. The CR95HF manages frame coding and decoding in reader mode for standard applications such as near field communication NFC, proximity and vicinity standards. The board also includes a 47mm x 34mm 13.56MHz inductive etched antenna and its associated tuning components. The user must connect a host to the board through the UART or the SPI connector. It allows to control the 13.56MHz CR95HF multi protocol transceiver IC from the host. The CR95HF acts as a slave. The host can configure the transceiver and send SPI or UART commands. The PLUG-CR95HF-B board is powered through the VPS pin.
