Functional Description
Operation Concept
The reader transmits a 13.56MHz carrier signal from its
antenna, the LC tank on the transponder side converts
the carrier energy to voltage form and supply to the tran-
sponder chip with an internal pump circuit. If the induced
energy is high enough, the pumped voltage reaches the
break-in voltage of the internal RC-oscillator, the tran-
sponder is actuated to transmit its internal data serially
by means of damping the LC tank.
The reader receives the transponder s data by means of
detecting the energy variation on its own antenna, and
recognize the information with a microcontroller.
The HT6720 has a built-in internal Voltage Limiter to
prevent excess power supply and RF levels induced by
the LC tank from damaging the device or causing the
device to function abnormally.
A total of 96 bits of OTP memory space is provided, from
which 64 bits wide are customer programmable, which
can be programmed using the specified programmer
supplied by Holtek. The pre-programmed ICs are also
available upon customer s request.
