EM4135
13.56MHz, ISO15693 Standard Compliant
Contactless Identification Device
General Description
Features
The EM4135 is a CMOS integrated circuit intended for use in
contactless Read/Write transponders.
ꢀ
ꢀ
ISO15693 Standard: Fully Compliant
Operating Frequency: 13.56MHz 7KHz
(ISM, world-wide licence free available)
2.4K bit EEPROM organised in 38 words of 64 bits
64-bit Unique Identifier (UID)
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.

Lock feature convert EEPROM words in Read Only
Support Application Field Identifier (AFI)
Power-check for EEPROM write operation
Resonant capacitor integrated on chip
28pF or 95pF (selectable by mask option)
No external supply buffer capacitor needed
-40 to +85°C temperature range

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.
Very low Power consumption (no battery needed)
Bonding pads optimised for flip-chip assembly
The resonant capacitor value is selected by metal mask.
