Description:
TK4100 is a CMOS integrated circuit for use in 125KHz read only RFID cards. It is can used with EM format. The circuit is powered by external coil in an alternating magnetic field, and via one of coil terminal to get its clock from this field.
Features:
1.64 bit memory array laser programmable
2.On chip voltage limiter
3.Full wave rectifier on chip
4.Large modulation depth due to a low impedance modulation device
5.Very small chip size convenient for implantation
6.On chip 480PF resonance capacitor On chip supply buffer capacitorz z Operating frequency 100 - 150kHz, typical frequency: 125KHz
7.Low power consumption
