IZ2817
Integrated Circuit for Contactless Identification System with ISO15693 data exchage protocol .
(functional equvivalent of SL2ICS11 ф.Philips)
IZ2817 - Integrated Circuit for contactless identification system with ISO15693 data exchage protocol, is purposed for usage in Radio Frequency Identification(RFID) Smart Label built-in cheap paper labels which serve basically for replacement of a standard strokecode. Radio-frequency identification is considered as more perfect system in comparison with stroke-code as it more flexible and can contain more information. Application spheres: identification of a luggage at the airports, books in libraries, clothes in shops, museum displays, a foodstuff etc. The external coil is connected to the microcircuit for creation of the contactless label. The built-in radio channel receives a signal induced in the aerial by external radiation This signal is used by power supply unit to generate supply voltage & by control unit to separate clocking signal.
Main features
• 192 bit (24 pages x 1 bytes) EEPROM ; • 100,000 memory program/erase cycles; • Contactless power supply & data transfer; • Operating field frequency 13,56 MHz; • Data transfer rate 56kbaud; • Built-in resonance capacitry 20 pF ≤CR≤ 27 pF; • Data exchange protocol meet international standard ISO 15693; • Anticollision function support with high speed of identification; • 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 without power supply (non-volantive memory); • Data transmittion by method of load modulation • Demodulation of the amplitude-modulated data received from the reader with a modulation index in limits from 10 to 30 %. • Temperature range -40 … +85 oC; • ESD protection up to 2000 V; • Latch current not less than 70 mA for 25 oC temperature;
