EMDB411 Fact Sheet

The EM4298 Development Kit provides the hardware
and software to demonstrate the features of EM4298
UHF reader encoder/decoder IC and simplify the
prototype development of UHF reader designs.
The EM4298 Development Kit hardware comprises two
printed boards; the demo board 2 equipped with the
ARM7 based microcontroller and EM4298 IC, and the
tag board.
General Function
The microcontroller controls the high level UHF protocol
processing by issuing the selected protocol commands to
the EM4298 IC. EM4298 IC generates corresponding Tx
serial signal that can be used as the UHF analog front
end modulator input. In the EM4298 Development Kit,
digital Tx signal is driving the UHF transponders directly.
In opposite direction, the UHF transponder “backscatter”
digital modulation signal is connected from the tag board
to the EM4298 IC I and Q digital channel inputs. EM4298
IC detects and samples such responses automatically so
that the microcontroller can process them.
The reader firmware can be upgraded via the USB port.
The EM4298 Development Kit supports the following
directly connected transponder ICs:
EM4122 / EM4222: iPX 64 bit Read Only UHF
EM4444: iPX 512 bit RW UHF transponder
EM4223: ISO18000-6A Read Only UHF transponder
