The EM4222 is a simple, read-only chip designed for low-cost tags. यसले 64-बिट सिरियल नम्बर बोक्छ जुन कारखानामा प्रोग्राम गरिएको छ. चिपले काम गर्न सक्छ 869 मेगाहर्ट्ज, 915 MHz वा 2.45 GHz. सम्म 120 ट्यागहरू प्रत्येक सेकेन्ड पढ्न सकिन्छ, र ट्यागहरूको पढ्ने दायरा छ 2 तिर 20 मिटर (6 तिर 60 खुट्टा).
EM4222 EM माइक्रोको EM4022 UHF चिपको सुधारिएको संस्करण हो, जुन धेरै वर्षदेखि बजारमा छ. सर्किटरीलाई सिलिकन वेफरमा कम से कम ठाउँ लिनको लागि अनुकूलित गरिएको छ. किनकी वेफरको मूल्य उस्तै छ, यसबाट थप चिपहरू काट्न सक्षम हुनुले कम इकाई लागत उत्पादन गर्दछ.
EM माइक्रोले ठूलो मात्रामा चिपको मूल्य बताउँछ (लाखौं एकाइहरू) तल हुनेछ 10 अमेरिकी सेन्ट. कम्पनीले कन्भर्टरहरू लेबल गर्न EM4222 बेचिरहेको छ, जसले एन्टेना जोड्नेछ र समाप्त ट्यागहरू बेच्नेछ. समाप्त ट्यागको लागि मूल्यहरू एन्टेनाको प्रकारमा निर्भर हुनेछ, लेबल स्टक, adhesive and other factors involved. The company says that the EM4222 chip can easily be adapted to make it compliant with ISO 18000-6A. That's because the chip's "front end" -- the analog part of the circuit, which runs the air interface -- doesn't need to change. Only the logic circuits, which runs the memory, bit encoding and so on, needs to be tweaked. The ISO 18000-6A version could also be adapted to handle and electronic product code. EM has supplied samples and supporting material to several label manufacturers, including ASK, Cardintell, IdealTag, KSW Microtec, Nagra ID, Rafsec, Sokymat, and others. The company is also working with a number of companies that produce readers. Among them are AWID and SAMSys and iPico, which helped EM in the development of the EM4222 chip. iPico will also provide reader modules to other OEM manufacturers like StId. A number of manufacturers, including Alien Technology and Matrics, have developed small RFID chips as a way to bring down the overall tag costs. Hitachi recently unveiled a prototype of the world's smallest chip (see Hitachi Unveils Smallest RFID Chip).
