EM Microelectronic EM4223

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).

DESCRIPTION

The air interface communication protocol is implemented according to ISO18000-6 type A. The code structure supports the effort of EPCglobal, Inc. as an industry accepted standard. It additionally incorporates the Fast Counting Supertag™ protocol for applications where the fast counting of large tag populations is required. The chip is frequency agile, and can be used in the range of 800 MHz to 2.5GHz for RF propagating field applications. Typical
