HITAG μ
Transponder IC
4.
Block diagram
The HITAG μ transponder ICs require no external power supply. The contactless interface
generates the power supply and the system clock via the resonant circuitry by inductive
coupling to the read/write device (RWD). The interface also demodulates data transmitted
from the RWD to the HITAG μ transponder IC, and modulates the magnetic field for data
transmission from the HITAG μ transponder IC to the RWD.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a capacity of up
to 1760 bit and is organized in blocks.
