EM MICROELECTRONIC - MARIN SA EM4223 Read-only UHF Radio Frequency Identification Device according to ISO IEC 18000-6 Description Features 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 factoryprogrammed 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. q q Typical Applications Benefits q q q q q Supply chain management (SCM) Tracking and tracing Asset control Licensing Auto-tolling q q q q q q q q q q q q 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 ‘Application Family Identifier’ (AFI) according to ISO Fast reading of user data during arbitration (no need to first take an inventory) Frequency independent: Typically used at 862 - 870 MHz, 902 - 950 MHz and 2.45 GHz Low voltage operation - down to 1.0 V Low power consumption Cost effective -40 to +85 °C operating temperature range Numbering scheme according to international standards Operates worldwide according to the local radio regulation Ideal for applications where long range and high-speed item identification is required Pin Assignment Pad No 1 2 3 3 EM4223 1 Name A Vss Vdd Function Connection to antenna (positive) Connection to antenna (negative) Positive connection (optional use) 2 Chip design is a joint development with RFIP Solutions Ltd.
