EM4169

128 bit Read/Write Contactless Identification Device

with OTP function

Description

Features

ꢀ

128 bit EEPROM organized in 8 words of 16 bits

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.

64 bit fixed code memory array laser programmed

OTP feature convert EEPROM words in read only

Power on Reset sequence

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.

Amplitude

Modulation (IC to reader and reader to IC)

ꢀ

Data encoding : Manchester or BI-Phase (FDX-B)

Transmission reader to chip: typically 65% AM

modulation

ꢀ

Data rate : 64 or 32 RF field periods per bit

(2 kBaud or 4 kBaud at 125 kHz)

78 pF resonant capacitor integrated on chip

100 to 150 kHz frequency range

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.

On-chip rectifier and voltage limiter

No external supply buffer capacitor needed

-40 to +85°C temperature range

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.

Very low Power consumption
