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.
