EM4102 - Read Only Contactless Identification

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.

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 consumption.

R EM MICROELECTRONIC - MARIN SA EM4102 Read Only Contactless Identification Device 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 EM4102 has several metal options which are used to define the code type and data rate.
