IZ2822

IZ2822 RFID circuit with read/write functions (Functionally compatible to MF0 IC U1X.Philips) General description The IZ2822 RFID circuit with read/write functions is purposed for usage in contactless plastic cards. Application areas: transference supervisory control system, antitheft systems, access control systems in buildings, restricted areas, burglar alarm, registration & identification systems in transportation & technological processes. External coil is connected to create contactless identifier mark. Build-in radio channel receive signal induced in antenna. This signal is used by power supply unit to generate supply voltage & by control unit to separate clocking signal. Main features 512 bit (16 pages x 4 bytes) EEPROM ; 100,000 memory program/erase cycles; Temperature range from minus 40 to plus 85 °С; ESD protection up to 2000 V; Latch current not less than 100 mA for 25 °С temperature; Contactless data & power supply transfer; Operating field frequency 13,56 MHz; Data transfer rate – 106 kbit/s; Build-in resonance capacitry 42,5 pF ≤ СR ≤ 57,5 pF; Anticollision function support, permit to process few identifier marks in receiving zone at the same time; Data exchange meet international standards ISO 14443-2, ISO 14443-3, type A; Internal DC voltage limitation to prevent identifier mark fail in power electromagnetic field.; Internal circuit clocking by means of separation of clock pulses from external electro- magnetic field; data storage ...
