The tag reader module is dedicated for automotive or industrial applications where information has to be transmitted
contactless.The tag reader module is a write/read (challenge/response) controller for applications that a demand high security
level.
The tag reader module is connected to a serial-tuned LC circuit that generates a magnetic field power supplying the tag. The
use of a synchronous sample and hold technique allows communication with all available tags using admittance switching
producing absorption of the RF field.
Load amplitude or phase shift modulation can be detected at high bit rates up to 8 kHz. The typical operational carrier frequency
of the tag reader module with an 8 MHz clock is 125 kHz.
