Description
EM4200 chip card 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 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 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.
Features
> Full compatible with EM4100/4102 and
EM4005/4105 communication protocols.
> 64 bit laser programmed ROM (128 and 96 bit option available)
> 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
> Several resonant capacitor integrated on chip
(0pF, 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 performances
Applications
> Animal Identification according to ISO11785 (FDX-B)
> Waste management standard (BDE)
> Access Control
> Logistics automation
> Anticounterfeiting
> Industrial transponder

IC card NFC CARD has the following advantages: 1) storage capacity is big. Magnetic card storage capacity is around 200 digital characters; IC card storage capacity depending on the type of small hundreds of characters, large millions of characters. 2) security good secrecy. IC card information can be read, modified, erased, but need a password. 3) the CPU card with data processing ability. When the data exchange with the card reader, but the data encryption, decryption, to ensure that the exchange of data accurate and reliable; While the magnetic card without this function. 4）Long service life.
