EM4223 - Read-only UHF Radio Frequency Identification

General 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.

Key Features

  • Air interface is ISO18000-6 type A compliant.
  • Supports EAN.
  • UCC and EPC™ data structures as defined by the Auto-ID center.
  • Supports Fast Counting Supertag™ mode.
  • 128 bit user memory license plate Group select by means of ‘.

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.
