EM card was offered by EM company , which its working frequency is 100 kHz ~ 150 kHz,and has read/write function of contactless RFID chip. It’s low consumption and can provide various data transmission rate and data encoding .
    Since EM chip is not only compatible with ISO 11784/11785 standard chip, also in line with ISO FDX / B animal identification standards, therefore, the chip can be widely use in various application management system, in particular, animal identification and tracking management.
     EM card with 32-bit password read / write protection, 32-bit unique ID code and 10 user codes. EM card has 512 bit EEPROM memory space, is divided into 16 sectors, each sector has 32 bit, One of the lock can change the data block of EEPROM into reading only

     Common EM chips are: EM4100, EM4102, EM4200, EM4305, EM4450...etc.

EM4102 chip:

General description

     The EM4102 (previously named H4102) is a CMOS integrated circuit for use in electronic Read Only RF Transponders. The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. By turning on and off the modulation current, the chip will send back the 64 bits of information contained in a factor programmed memory array.      The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The H4102 has several metal options which are used to define the code type and data rate. Data rates of 64, 32 and 16 periods of carrier frequency per data bit are available. Data can be coded as Manchester, Biphase or PSK. Due to low power consumption of the logic core, no supply buffer capacitor is required. Only an external coil is needed to obtain the chip function. A parallel resonance capacitor of 78pF is also integrated.

Features:

> 64 bit memory array laser programmable
> Several options of data rate and coding available
> On chip resonance capacitor
> On chip supply buffer capacitor
> On chip voltage limiter
> Full wave rectifier on chip
> Large modulation depth due to a low impedance modulation device
> Operating frequency 100 – 150 kHz
> Very small chip size convenient for implantation
> Very low power cons

Applications:

• Anticounterfeiting
• Access control
• Industrial transponder
