The MIKROE-1434 RFid Click Board integrates CR95HF 13.56 MHz contactless transceiver as well as trace antenna.Theclickis designed to run on a 3.3V power supply only. It communicates with the target MCU via mikroBUS UART (TX, RX), SPI (MISO, MOSI, SCK, CS) INT, RST, PWM and AN lines.
CR95HF Integrated transceiverThe CR95HF has 2 operating modes: Wait for Event (WFE) and Active.
In Active mode, the CR95HF communicates actively with a tag or an external host. WFE mode includes four low consumption states: Power-up, Hibernate, Sleep and Tag Detector. The transceiver can switch from one mode to another.
The Hibernate state has the lowest power consumption out of the four states (1 uA typ. 5 uA max.).
