LRIS64K Datasheet, PDF (69/100 Pages) STMicroelectronics – 64 Kbit EEPROM tag IC at 13.56 MHz with 64-bit UID and password based on ISO/IEC 15693 and ISO/IEC 18000-3 Mode 1

Write DSFID
On receiving the Write DSFID request, the LRIS64K programs the 8-bit DSFID value to its
memory. The Option_flag is supported.
During write cycle W_t, there should be no modulation (neither 100% nor 10%). Otherwise,
the LRIS64K may not write correctly the DSFID value in memory. The W_t time is equal to
t_1nom + 18 × 302 µs.
