Preliminary EM4222
Read-only UHF Identification Device
Description
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 pre-
programmed 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-collision protocol.
The chip is frequency independent and is to be used for
RF coupled applications. A reading range from 2m to
20m and reading rates up to 120 tags/second can be
achieved, depending upon the system configuration. The
Tag Talk First (TTF) protocol enables very simple reader
implementation.

u.cFor ICs to be used in mass production, the customer must define its options with the control ROM bit definition. Using this
t4information, EM Microelectronic-Marin S.A. will define a complete new Part Number for ordering.
