Features of TK4100 chip card

The TK4100 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 factory 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

-Operating frequency 100 ~150 kHz, (125kHz)

-Very small chip size convenient for implantation

-Very low power consumption
