Description



Description

The chip 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 pre-programmed 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 EM4123 is frequency independent and can be used for RF coupled applications where reading ranges in excess of 10 m and reading rates of 120 tags per second at 256 kbit/s can be attained. The circuit is backscattering data using load modulation. Therefore the reader should be able to detect ASK and PSK modulated carrier.

Benefits:
* Anti-collision suited for fast moving objects
* Very low current consumption, long range solution
* Easy to use, only pure CW RFID reader needed (No dense reader mode issue)
* Protocol and coding backward compatible with EM4122 and EM4222
* Low cost solutions
