512 bit Read/Write Contactless Identification Device
General Description
EM4469 and EM4569 are CMOS RFID integrated circuits
intended
for
use
in
electronic
transponders.
The RFID 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 from its internal
EEPROM 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 100% AM
modulation of the 125 kHz magnetic field.
There are several data rate and data encoding options
available. Options are stored in EEPROM Configuration
word. Read and write access to EEPROM can be
protected by 32-bit password. All EEPROM words can be
write protected by setting lock bits which transform them
in read-only.
It contains factory programmed and locked 32 bit UID
number, chip type and customer code.
EM4569 is completely compatible with EM4469. However,
EM4569 has bumped enlarged pads intended for direct
connection of coil to big bumps. EM4569 also has an
extended reading range which makes it particularly
suitable for animal tracking applications.
