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 preprogrammed 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 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.

General
The EM4100 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.
Data Modulator
The data modulator is controlled by the signal Modulation
Control in order to induce a high current in the coil. In the
PSK version, only COIL2 transistor drives this high current.
In the other versions, both coil1 and coil2 transistors drive it
to Vdd. This will affect the magnetic field according to the
data stored in the memory array.
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.
Resonance Capacitor
This capacitor can be trimmed in factory by 0.5pf steps to
achieve the absolute value of 74pf typically. This option,
which is on request, allows a smaller capacitor tolerance on
the whole of the production.
Functional Description
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.
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.

EM4100
Memory Array for Manchester & Bi-Phase encoding ICs
The EM4100 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.

Memory Array for PSK encoding ICs
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.
9 header bits
Code Description
Manchester
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).
10 line parity
bits
Biphase Code
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).
4 column parity bits
The header is composed of the 9 first bits which are all
mask 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.
PSK Code
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).
