EM MICROELECTRONIC - MARIN SA EM4123 Read-only UHF RFID IC Features 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 chip 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 chip is backscattering data using load modulation. Therefore the reader should be able to detect ASK and PSK modulated carrier. Factory programmed 64 bit ID number High data rate: Up to 256 kbit/s Frequency independent: Typically used at 869 MHz, 902 - 960 MHz (versions 001 to 099) On-chip oscillator On-chip rectifier Low voltage operation - down to 1.0 V at ambient temperature Tag Talk Only protocol (TTO) Low power consumption -40° to +85° C operating temperature range Typical Configuration Typical Applications The chip is ideal for applications where long range, highspeed item identification is required: Supply chain management Tracking and tracing Access control Asset control Licensing Auto-tolling Animal tagging Sports event timing VSS A 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 UHF transponders can be implemented using an EM4123 chip and an open dipole antenna.
