Read-only UHF RFID IC

Description

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.

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
