EM4200

128 bit Read Only Low Frequency Contactless Identification Device

EM4200 is a CMOS integrated circuit intended for use in electronic Read Only RF transponders. It is designed to replace seamlessly the EM Microelectronic-Marin Read Only ICs EM4100/4102 and EM4005/4105.

The circuit is powered by an external coil placed in an electromagnetic field and gets its master clock from the same field. By turning on and off the modulation current, the chip sends back the unique code contained in a factory
pre-programmed laser ROM.

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 IC offers also different resonant capacitor versions, selectable by mask option (0pF, 75pF and 250pF) providing the same reading performances to ensure seamless replacement.

Features
