escription
The ZMD41201 is a fully integrated 13.56 MHz ISO
15693 compliant wireless tag transponder circuit. The
on-chip EEPROM can be written in downlink direction
and read in uplink direction by inductive coupling from
a reader. The power is also extracted from the reader
through inductive coupling. Due to the on-chip tank
capacitor, the ZMD41201 only needs an external coil.
The chip extracts its clocks from the incoming 13.56
MHz oscillation and the data from the envelope of the
oscillation. Data is transmitted by load-modulating the
incoming magnetic field.

unctional Operation
Communication Procedure
1. The tag is powered up by the operating field generated by the reader
2. The tag is ready in idle mode
3. The reader sends a command
4. The tag responds to the command

Downlink
Uplink
Modulation
10% or 100% selectable
ASK or FSK selectable
Data Rate Selections
Long distance: 1.65k bit/s
or
fast transmission: 36.48k bit/s
Low: 6.65k bit/s
or
high: 26.6k bit/s*
Any combination is possible
(ISO/IEC 15693 compliant)
*) High data rate is slightly depending on selected modulation (ASK or FSK).
