EM4223 Datasheet | EM Microelectronic

EM MICROELECTRONIC - MARIN SA Read-only UHF Radio Frequency Identification Device according to ISO IEC 18000-6 Description The EM4223 chip is used in UHF passive read-only transponder applications. The chip derives its operating power from an RF beam transmitted by the reader, which is received and rectified by the chip. It transmits its factory-programmed code back to the reader by varying the amount of energy that is reflected from the chip antenna circuit (passive backscatter modulation). The air interface munication protocol is implemented according to ISO18000-6 type A. The code structure supports the effort of EPCglobal, Inc. as an industry accepted standard. It...
