| R EM MICROELECTRONIC - MARIN SA EM4034 13.56MHz, ISO15693 Standard Compliant Contactless RW Identification Device General Description The EM4034 is a CMOS integrated circuit intended for use in contactless Read/Write transponders. The IC is a member of ISO 15693 standard compliant. Passive Read/Write RF Tags operating at 13.56MHz. The user's configurable 448 bit EEPROM memory contained in the chip is organised in 14 words of 32 bits, each word can be irreversibly locked. The memory contains a unique serial number. The ISO 15693 anticollision algorithm allows operating more tags in the field simultaneously. IC is completely ISO 15693 compliant since it includes all ISO15693 mandatory features. Features ISO15693 Standard: Fully compliant Support all mandatory and some optional ISO/IEC 15693 features Operating Frequency: 13.56MHz 7kHz (ISM, world-wide licence free available) ISO/IEC 15693 anti-collision algorithm allowing more tags in reader field at the same time 64-bit Unique Identifier (UID) 448 bit EEPROM organised in 14 words of 32 bits Lock feature convert EEPROM words in Read Only Secure transfers with Login command Smart Electronic Article Surveillance On chip resonant capacitor No external supply buffer capacitor needed -40 to +65C temperature range Bonding pads optimised fro flip-chip assembly Applications Access Control Ticketing Asset management Typical Operating Configuration C1 EM4034 C2 Fig. 1 Block Diagram L2 VPOS Lr Cr CBU RECTIFIER L1 R E G U L A T O R Vdd POWER MONITOR POR PCK CLOCK EXTRACTOR RECEIVED CLOCK EEPROM AM DEMODULATOR PULSE LOGIC MOD MODULATOR LIMITER Fig. 2 Copyright (c) 2004, EM Microelectronic-Marin SA 1 www.emmicroelectronic.com |
