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 userâs 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.
