electromagnetic field. A resistor is switched in parallel to
the resonant circuit formed by the integrated tuning
capacitor and the external coil, to amplitude modulate
the electromagnetic field. Encoding of the 128 bits ID
and data rate can be defined by setting the
corresponding EEPROM bits.
High quality factors can be applied as the frequency can
be tuned over a range of +/-10% to +/-0.5% accurate
after assembly, by changing the value of the tuning
capacitor up to +/- 2pF.
The EEPROM is configured as 11 words of 16 bits.
Words 1 to 8 form the ID and are continuously read out
during normal operation.
individually locked, or the complete EEPROM can be set
to read only.
The transponder can be written over the full range from
0% to 60% of the normal reading distance. The
transponder stops modulating when receiving an AM
asynchronous pattern. It will then synchronize on the
first bit it receives.
transmitted using Return to One modulation, including
direct word addressing and multiple security checks.
Data integrity is guaranteed by critical read out after
programming.
