DESCRIPTION
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. Typical Operating Configuration FEATURES
