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.
Typical Applications
q Supply chain management (SCM)
q Tracking and tracing
