DESCRIPTION
A preprogrammed code is transmitted to the reader by varying the amount of energy that is reflected back to the reader. The chip is frequency independent and is to be used for RF coupled applications. A reading range from 2m to 20m and reading rates up to 120 tags/second can be achieved, depending upon the system configuration. The Tag Talk First (TTF) protocol enables very simple reader implementation. FEATURES
Factory programmed 64 bit unique ID number High data rate: Up to 256 kbit/s Frequency independent: Typically used at 869 MHz, 902 - 928 MHz, 2.45 GHz On-chip oscillator On-chip rectifier Low voltage operation - down to 1.0 V Low power consumption Cost effective -40 to +85°C operating temperature range Available in die form Operating Configuration UHF transponders can be implemented using an EM4222 chip and an antenna. Typical APPLICATIONS
The EM4222 is ideal for applications where long range, high-speed item identification is required: Supply chain management (SCM)...
