com EM MICROELECTRONIC - MARIN SA EM4444 512 bit, Read/Write UHF Identification Device Description The EM4444 is used in passive UHF Read/Write transponder applications.
It is powered up by an RF beam transmitted by the reader, which is received and rectified to generate a supply voltage for the chip.
A pre-programmed ID code or other data is transmitted back to the reader by varying the amount of energy that is reflected back to the reader.
It implements the robust and fast anti-collision protocol full compliant with the EM Microelectronic UHF read-only and read/write tags.
Data is written to the tag in 64 bit blocks by commanding the chip after its presence had been detec...
