EM4102

Read Only Contactless Identification Device

Description

Features

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.

□

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 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.

Applications

□

Animal implantable transponder

Animal ear tag

Industrial transponder

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.

resonance capacitor of 78 pF is also integrated.

Handling Procedures

This device has built-in protection against high static

voltages or electric fields; however, anti-static precautions

must be taken as for any other CMOS component. Unless

otherwise specified, proper operation can only occur when

all terminal voltages are kept within the voltage range.

Unused inputs must always be tied to a defined logic

voltage level.

The EM4102 contains 64 bits divided in five groups of

information. 9 bits are used for the header, 10 row parity

bits (P0-P9), 4 column parity bits (PC0-PC3), 40 data bits

(D00-D93), and 1 stop bit set to logic 0.

Functional Description

General

The EM4102 is supplied by means of an electromagnetic

field induced on the attached coil. The AC voltage is

rectified in order to provide a DC internal supply voltage.

When the last bit is sent, the chip will continue with the

first bit until the power goes off.

Full Wave Rectifier

The AC input induced in the external coil by an incident

magnetic field is rectified by a Graetz bridge. The bridge

will limit the internal DC voltage to avoid malfunction in

strong fields.

32 data bits

Clock Extractor

One of the coil terminals (COIL1) is used to generate the

master clock for the logic function. The output of the clock

extractor drives a sequencer.

D90 D91 D92 D93 P9 10 line parity

PC0 PC1 PC2 PC3 S0 bits

4 column parity bits

Sequencer

The sequencer provides all necessary signals to address

the memory array and to encode the serial data out.

Three mask programmed encoding versions of logic are

available. These three encoding types are Manchester,

biphase and PSK. The bit rate for the first and the second

type can be 64 or 32 periods of the field frequency. For

the PSK version, the bit rate is 16.

The sequencer receives its clock from the COIL1 clock

extractor and generates every internal signal controlling

the memory and the data encoder logic.

The header is composed of the 9 first bits which are all

programmed to "1". Due to the data and parity

organisation, this sequence cannot be reproduced in the

data string. The header is followed by 10 groups of 4 data

bits allowing 100 billion combinations and 1 even row

parity bit. Then, the last group consists of 4 event column

parity bits without row parity bit. S0 is a stop bit which is

written to "0"

Bits D00 to D03 and bits D10 to D13 are customer

specific identification.

These 64 bits are outputted serially in order to control the

modulator. When the 64 bits data string is outputted, the

output sequence is repeated continuously until power

goes off.

Data Modulator

The data modulator is controlled by the signal Modulation

Control in order to induce a high current in the coil. The

coil 2 transistor drives this high current. This will affect the

magnetic field according to the data stored in the memory

array.

R

EM4102

Memory Array for PSK encoding ICs

Biphase Code

The PSK coded IC's are programmed with odd parity for

P0 and P1 and always with a logic zero.

The parity bits from P2 to P9 are even.

The column parity PC0 to PC3 are calculated including

the version bits and are even parity bits.

At the beginning of each bit, a transition will occur. A logic

bit “1” will keep its state for the whole bit duration and a

logic bit “0” will show a transition in the middle of the bit

duration (see Fig. 7).

PSK Code

Code Description

Manchester

Modulation switch goes ON and OFF alternately every

period of carrier frequency. When a phase shift occurs, a

logical "0" is read from the memory. If no shift phase

occurs after a data rate cycle, a logical "1" is read (see

Fig. 8).

There is always a transition from ON to OFF or from OFF

to ON in the middle of bit period. At the transition from

logic bit “1” to logic bit “0” or logic bit “0” to logic bit “1” the

phase change. Value high of data stream presented

below modulator switch OFF, low represents switch ON

(see Fig. 6).
