EM MICROELECTRONIC - MARIN SA

EM4123

Read-only UHF RFID IC

Features

Description

Factory programmed 64 bit ID number

High data rate: Up to 256 kbit/s

Frequency independent: Typically used at 869 MHz,

902 - 960 MHz (versions 001 to 099)

On-chip oscillator

On-chip rectifier

Low voltage operation - down to 1.0 V at ambient

temperature

The chip is used in passive UHF read-only transponder

applications. It is powered up by an RF beam transmitted

by the reader, which is received and rectified to generate a

supply voltage for the chip. A pre-programmed code is

transmitted to the reader by varying the amount of energy

that is reflected back to the reader. It implements a robust

and fast anti-collision protocol. The chip is frequency

independent and can be used for RF coupled applications

where reading ranges in excess of 10 m and reading rates

of 120 tags per second at 256 kbit/s can be attained.

The chip is backscattering data using load modulation.

Therefore the reader should be able to detect ASK and

PSK modulated carrier.

Tag Talk Only protocol (TTO)

Low power consumption

-40° to +85° C operating temperature range

Typical Configuration

Typical Applications

The chip is ideal for applications where long range, high-

speed item identification is required:

Supply chain management

Tracking and tracing

Access control

Asset control

Licensing

Auto-tolling

Animal tagging

Sports event timing

V_SS

UHF transponders can be implemented using an EM4123

chip and an open dipole antenna.

Benefits

Anti-collision suited for fast moving objects

Very low current consumption, long range solution

Easy to use, only pure CW RFID reader needed (No

dense reader mode issue)

Protocol and coding backward compatible with

EM4122 and EM4222

Low cost solutions
