Description
The MIKROE-1434 RFid Click Board integrates CR95HF 13.56 MHz contactless transceiver as well as trace antenna. The click is 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 transceiver
The CR95HF has 2 operating modes: Wait for Event (WFE) and Active.
The 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.).
