General Description

EM4200/ H4200 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.

Comparing to EM4100/ 4102 and EM4005/ 4105, the chip provides higher reading range performances and presents on its coil terminals bigger resonant capacitor (210pF and 250pF selectable by mask option).

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 will send back the unique code contained in a factory pre-programmed laser ROM.

Feature
* Fully compatible with EM4100/ 4102 and EM4005/ 4105 communication protocols
* Several options of data rate and data encoding: Manchester, Biphase, PSK and FSK
* Several resonant capacitor integrated on chip (75pF, 210pF or 250pF mask option)
* 100 to 150 kHz frequency range
* On-chip rectifier and voltage limiter
* No external supply buffer capacitor needed
* -40°C to +85°C temperature range
* Very low power consumption and high performance
