IC/Module: CR95HF 13.56 MHz Contactless Transceiver
The integrated CR95HF transceiver IC intended for contactless applications. In the Reader mode, it manages frame coding and decoding for standard applications, like near field communication (NFC), proximity and vicinity standards. The embedded Analog Front End, which provides the 13.56 MHz air interface.
Communication Interface: SPI or UART
RFid Click Board™ uses the mikroBUS UART (TX, RX) or SPI (MISO, MOSI, SCK, CS) lines for main communication with the target boards MCU. The communication interface is selectable using the two SMD jumpers. For SPI, the SMD jumpers will remain in the default (A) position, but to choose UART, it is necessary to solder the SMD jumpers in (B) position. If set to UART mode, interrupt pins are not usable.
