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
the last page of this data sheet. All specified parameters
and descriptions are applicable for the EM4169 device.
