Overview

EM MICROELECTRONIC - MARIN SA Preliminary EM4222 Read-only UHF Identification Device Description The EM4222 is used in passive UHF read-only transponder applications.
It is powered up by an RF beam transmitted by the reader, which is received and rectified to generate a supply voltage for the chip.
A preprogrammed code is transmitted to the reader by varying the amount of energy that is reflected back to the reader.
It implements a robust and fast anti-collision protocol.
The chip is frequency independent and is to be used for RF coupled applications.
A reading range from 2m to 20m and reading rates up to 120 tags/second can be achieved, depending upon the system configuration.
The Tag Tal...
