EM4469
Description
EM4469 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders.
The IC is powered by picking the energy from a continuous 125 k Hz 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. mands and EEPROM data updates can be executed by 100% AM modulation of the 125 k Hz 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.
