EM4223
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 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.
