EM4369 is a CMOS integrated circuit intended for use in

electronic Read/Write RF transponders. It is functionaly

equivalent to the EM4269 and compatible with the

EM4469/4569 family. It is intended for direct connection of

coil to big bumps.

Comparing to EM4469/4569 family, the changes are the

following:

New configuration bit co₂₅(configuration word), which

inverts data input to the encoder.

Writing to Protection Word is modified.

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

reads out data from its internal EEPROM memory and

sends it out by switching on and off a resistive load in

parallel to the coil.

Very low Power consumption

Big pads (200 μm x 400 μm) for direct connection of

coil using bumps

Resonant capacitor with options 80pF, 250pF and

330pF integrated on chip

Commands and EEPROM data updates can be executed

by 100% AM modulation of the 125 kHz magnetic field.

Applications

There are several data rate and data encoding options

available. The IC Options are stored in EEPROM

configuration word (word 4). Read and write access to

EEPROM can be protected by 32 bit password.

Access Control

Animal Identification according to ISO FDX-B

Material Logistics

All EEPROM words can be write protected by setting lock

bits which transform them in read-only.

It contains a factory programmed and locked 32 bit UID

number, chip type and a customer code.

The on-chip resonant capacitor value is selected by metal

mask (three different options).
