EM4100

Read Only Contactless Identification Device

Description

Features

The EM4100 (previously named H4100) 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 y pre-

programmed memory array.

□

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

The programming of the chip is performed by laser fusing

of polysilicon links in order to store a unique code on each

chip.

□

Operating frequency 100 - 150 kHz

Very small chip size convenient for implantation

Very low power consumption

The EM4100 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 74 pF is also integrated.
