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. 


1. Full compatible with EM4100/4102 and EM4005/4105 communication protocols.
2.128 bit laser programmed ROM (64 and 96 bit option available)
3. Several options of data rate and data encoding:
     Manchester 32 and 64 RF clocks per bit
    Biphase 32 and 64 RF clocks per bit
    PSK 16 RF clocks per bit (subcarrier RF/2)
    FSK2 50RF clocks per bit
4.Several resonant capacitor integrated on chip (0pF, 75pF or 250pF mask option)
5.100 to 150 kHz frequency range
6. On-chip rectifier and voltage limiter
7. No external supply buffer capacitor needed
8. -40°C to +85°C temperature range
