125Khz Yellow Digital Rfid Key Fob Security Ultra High Frequency Easy Carry

    EM4200 is a CMOS integrated circuit intended for use in electronic Read Only RF transponders. It is designed to replace directly the EM Microelectronic-Marin Read Only ICs EM4100/4102 and EM4005/4105.
   Compared to EM4100/4102 and EM4005/4105, this chip provides higher reading range performances and presents on its coil terminals bigger resonant capacitor (210pF and 250pF selectable by mask option).
   The 128 bit unique code is stored in laser programmed ROM. Several options are available to use 64, 96 or 128 bits of ROM.
   The circuit is powered by an external coil placed in an electromagnetic field and gets its master clock from same field. By turning on and off the modulation current, the chip will send back the unique code contained in a factory pre-programmed laser ROM.

   This RFID Key fob is made of refined mold, advanced high temperature anti-corrosion material injection pressure, internal EM4200 chip package, by filling an epoxy resin, a combination of ultrasonic welding, can be waterproof, easy to carry features.
