EM4022

Multi Frequency Contactless Identification Device

Anti-Collision compatible with BTG's Supertag Category Protocols

Description

The EM4022 (previously named P4022) chip implements

patented anti-collision protocols for both high frequency

and low frequency applications. It is even possible to

identify transponders with identical codes, thereby

making it possible to count identical items. The chip is

typically used in “passive” transponder applications, i.e. it

does not require a battery power source. Instead, it is

powered up by an electromagnetic energy field or 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.

This is done by modulating an antenna or coil, thereby

effectively varying the load seen by the reader.

Typical Applications

Access control

Animal tagging

Asset control

Sports event timing

Licensing

Electronic keys

Auto-tolling

Features

Implements all BTG anti-collision protocols:

Fast SWITCH-OFF, SLOW-DOWN, and

FREE-RUNNING

Can be used to implement low frequency

inductive coupled transponders, high frequency

RF coupled transponders or bi-frequency

transponders

Reading 500 transponders in less than one

second for high frequency applications

Factory programmed 64 bit ID number

Data rate options form 4 kbit/s to 64 kbit/s

Manchester data encoding
