EM4169
128 bit Read/Write Contactless Identification Device
with OTP function
Description
EM4069 (previously named P4069) is a CMOS integrated
circuit intended for use in electronic Read/Write RF
transponders, with an optional lock function to disable
EEPROM write operations.
The IC is powered by picking the energy from a
continuous 125 kHz magnetic field via an external coil,
which together with the integrated capacitor form a
resonant circuit. The IC read out data’s from its internal
EEPROM or ROM and sends it out by switching on and
off a resistive load in parallel to the coil. Commands and
EEPROM data updates can be executed by AM
modulation of the 125 kHz magnetic field.
At power–up the EM4069 goes in default mode in which it
constantly (without any pause) transmits 128 bits from the
EEPROM. Upon transmission of a specific command, the
64 bits unique laser code is output. Additional commands
for writing and lock data in EEPROM are available.
The EM4169 (previously named P4169) is the same
device but with large bumps (mega pads) as indicated on
page 13 of this data sheet. All specified parameters and
descriptions are applicable for the EM4169 device.

Functional Description
The IC builds its power supply through an integrated
rectifier. When it is placed in a magnetic field the DC
internal voltage starts to increase.
As long the power supply is lower than the power on reset
(POR) threshold, the circuit is in reset mode to prevent
unreliable operation. In this mode the modulator switch is
off.
After the supply voltage cross the POR threshold, the
circuit goes in read mode and transmits periodically the
128 data bits from EEPROM.
The power on reset is designed with a typically 250mV
hysteresis. The specified value in the DC electrical
characteristic table indicates the high level-switching
threshold. Ones the supply voltage had reached this level,
the device work in read mode and reenter in reset mode if
the supply voltage decrease under the lower threshold
(~VPOR – 250mV).
In read mode the IC transmits periodically either the 128
data bits from EEPROM or 64 data bits from ROM if
command 2 has been sent. The bits are Manchester or BI-
phase coded and issued by switching the modulator load in
parallel to the coil ON and OFF. The read out process is
repeated continuously without any pause as long as power
level is greater than the POR threshold low.
While the IC is operating in read mode it checks the coil
signal once every bit period. If it detects a certain reader
induced amplitude modulation of magnetic field it stops
modulating and waits for a command word. In the case the
EEPROM write command is detected the contents of
selected EEPROM word is modified. Read ROM command
will change the output sequence to the data provided by
the laser ROM continuously.
The Reset command returns to the initial mode as after a
Power on Reset.
Block description
Power On Reset (POR)
wwwW.DhaetanShteheet4UE.cMo4m069 with its attached coil enters an
electromagnetic field, the built in AC/DC converter will
supply the chip. The DC voltage is monitored and a Reset
signal is generated to initialise the logic. The Power On
Reset is also provided in order to make sure that the chip
will start issuing correct data.
Hysteresis is provided to avoid improper operation at the
limit level.

Clock Extractor
The Clock extractor will generate a system clock with a
frequency corresponding to the frequency of the RF field.
The system clock is used by a sequencer to generate all
internal timings.
Data Extractor
The transceiver generated field will be amplitude
modulated to transmit data to the EM4069. The Data
extractor demodulates the incoming signal to generate
logic levels, and decodes the incoming data.
Modulator
The Data Modulator is driven by the serial data output from
the transceiver. The modulator will draw a large current
from both coil terminals, thus amplitude modulating the RF
field according to the selected memory data.
AC/DC Converter and Voltage Limiter
The AC/DC converter is fully integrated on chip and will
extract the power from the incident RF field. The internal
DC voltage will be clamped to avoid high voltage in strong
RF fields.
Lock All / Lock Memory Area
The EM4069 can be converted to a Read Only chip or be
configured to Read/Write and Read Only Areas by
programming the protection word. This configuration can
be locked by write inhibiting the Write Protection Word.
Great care should be taken in doing this operation as there
is no further possibility to change the Write Protection
Word. The Control Word can also be protected in the
same way thus freezing the writing operation.

ROM organization
The ROM is composed of 64 bits divided in a 9-bit header, 10 nibbles of 4 data bits and 1 row even parity bit, 4 column even
parity bits, and 1 stop bit. The Read ROM command will output the contents of the ROM, starting with bit-0. When bit-64 is
output, the sequence continues with bit-0.
Data in ROM is written by laser programming during manufacturing to form a unique identification code.
Figure below presents the ROM data structure. Bits P0 to P9 are row parity bits and bits PC0 to PC3 are column parity bits.
Parity is even so that a 9 bits set to logic one header can not be reproduced in a data stream.

Command description
The EM4069 operates in different modes. The default following a Power on Reset is Read EEPROM mode, and by means of
different commands, the circuit can switch to the following modes :
read access to ROM
write access to 16 bits of EEPROM
write access to configuration word
read access to configuration word
The reader has to generate the commands, which have to be decoded by the EM4069.

Command 5
rcw
1111 0000
Read configuration word
Commands rst, rROM and rcw affect readout. An eight-bit pattern has to be sent to execute them. Write commands are longer
since associated address and data have to be sent. The leftmost bit in command bit pattern is transferred first.
Command 1: Reset command
During activation of the transponder a return to default
mode is possible from any mode with the reset command.
Command 2 : Read out of ROM 64 Bits
After activation of command 2, the 64 bit ROM data will be
read out cyclically. This mode will be active until power
down or reset command.
Command 3 : Write 16 Bit EEPROM word
After activation of command 3, a 16-bit EEPROM word can
be written. Data transmission will be secured by CRC
check information, which has to be calculated by the reader
and which will be checked by the EM4069.
Command 4 : Write configuration word
Command 4 has the same structure as command 3. The
16-bit configuration word is written by this command. A
partial locking (write inhibit) of the 128 bit memory is
possible in blocks of 16 bits (16 bit word becomes read-
only).
The bits of configuration word are OTP (one time
programmable) so once a certain bit in configuration word
is set it cannot be reset.
