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. 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 78 pF is also integrated.
