13.56MHz, ISO15693 Standard Compliant
Contactless Identification Device
General Description
The EM4135 is a CMOS integrated circuit intended for use in
contactless Read/Write transponders.
The 2.4k bit EEPROM memory contained in the chip is
organized in 38 words of 64 bits, each word can be irreversibly
locked. The memory contains a unique serial number (UID).
The ISO 15693 anticollision algorithm allows operating more
tags in the field simultaneously. The EM4135 is completely
ISO15693 compliant since it includes all ISO15963 mandatory
features.
The 64 bits UID as defined in ISO15693 standard is factory
programmed and locked. It includes a 6 bits chip type and a
10 bits customer code made specific on request.
The resonant capacitor value is selected by metal mask.
