3.6 Transponder addressing
RF300: Address mapping of OTP memory on the RF300 transponder
R/W EEPROM memory and OTP memory is only available once on the transponder.
The following table shows the mapping of addresses on the transponder.
Data can be read via the R/W address or the OTP address.
Note
Enabling write protection
Write access to addresses starting at FF80 to FF93 activates the write protection (OTP
function) on the EEPROM user memory. This operation is not reversible. Switching on write
protection must always take place in ascending order without gaps, starting at address FF80.
