Read Only Contactless Identification Device  
Description  
Features  
The EM4100 (previously named H4100) is a CMOS  
integrated circuit for use in electronic Read Only RF  
Transponders. The circuit is powered by an external coil  
placed in an electromagnetic field, and gets its master  
clock from the same field via one of the coil terminals. By  
turning on and off the modulation current, the chip will send  
back the 64 bits of information contained in a factor y pre-  
programmed memory array.  
64 bit memory array laser programmable  
Several options of data rate and coding available  
On chip resonance capacitor  
On chip supply buffer capacitor  
On chip voltage limiter  
Full wave rectifier on chip  
Large modulation depth due to a low impedance  
modulation device  
The programming of the chip is performed by laser fusing  
of polysilicon links in order to store a unique code on each  
chip.  
Operating frequency 100 - 150 kHz  
Very small chip size convenient for implantation  
Very low power consumption  
The EM4100 has several metal options which are used to  
define the code type and data rate. Data rates of 64, 32  
and 16 periods of carrier frequency per data bit are  
available. Data can be coded as Manchester, Biphase or  
PSK.  
Due to low power consumption of the logic core, no supply  
buffer capacitor is required. Only an external coil is needed  
to obtain the chip function. A parallel resonance capacitor  
of 74 pF is also integrated.
