EM4222 - EM Microelectronic

EM4222 Read-Only UHF Identification

The EM4222 is used in passive UHF read-only 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 preprogrammed code is transmitted to the reader by varying the amount of energy that is reflected back to the reader. It implements a robust and fast anti-.
