RF Tag Memory Map (EEPROM type)
When RF Tag service life warning management is enabled, the number of rewrites is saved in hexa-
decimal in the eight bytes from addresses 03E0 to 03E8 hex. Therefore, when RF Tag service life
warning management is enabled, it will be possible to use only 992 bytes from addresses 0000 to
03DF hex.
When RF Tag service life warning management is disabled and an ID Controller, Handheld Reader/
Writer, or controller made by another company is used, it will be possible to use all 1,000 bytes from
addresses 0000 to 03E7 hex.
Note: If RF Tag service life warning management is not used, addresses 03E0 to 03E7 hex can be
used as user memory. Be sure to disable RF Tag service life warning management of the FL
Remote ID to use these addresses.
RF Tag service life management is a function of FL Remote ID. If an ID Controller, Handheld Reader/writer, or controller
made by another company is used, do not overwrite address 03E0 to 03E7 hex when using this function unless initializ-
ing unused RF Tags.
