Product short data sheet
COMPANY PUBLIC
The HITAG S Transponder requires 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 S Transponder, and modulates the magnetic field
for data transmission from the HITAG S Transponder to the RWD.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a capacity up to
2048 bit and is organized in 64 Pages consisting of 4 Bytes each (1 Page = 32 Bits).
