EM4022  
Multi Frequency Contactless Identification Device  
Anti-Collision compatible with BTG's Supertag Category Protocols  
Description  
Features  
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.  
ꢀ
ꢀ
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
