Additional preview pages of the EM4222 datasheet.

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.

Factory programmed 64 bit unique ID number High data rate: Up to 256 kbit/s Frequency independent: Typically used at 869 MHz, 902 - 928 MHz, 2.45 GHz On-chip oscillator On-chip rectifier Low voltage operation - down to 1.0 V Low power consumption Cost effective -40 to +85°C operating temperature range Available in die form Operating Configuration UHF transponders can be implemented using an EM4222 chip and an antenna.
