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.

Compatible with UHF read-only and read/write tags (EM4222, EM4122, EM4442) Factory programmed 64 bit serial ID number 7 pages of user programmable and lockable memory (64-bit pages) EEPROM data pages can be transmitted with ID in Tag-Talks-only (TTO) mode. Can be used as OTP device High reading data rate up to 256 kbit/s Frequency independent: typically used at 315 MHz, 433 MHz, 869 MHz, 902 - 928 MHz and 2.45 GHz On-chip oscillator Low voltage operation down to 1.3V -40 to.
