Description

Description
The
ST25DV04K, ST25DV16K
and
ST25DV64K
devices are NFC RFID tags offering respectively 4 Kbit, 16 Kbit,
and 64 Kbit of electrically erasable programmable memory (EEPROM).
ST25DV04K, ST25DV16K
and
ST25DV64K
offer two interfaces. The first one is an I
2
C serial link and can be operated from a DC power supply.
The second one is a RF link activated when
ST25DV04K, ST25DV16K
or
ST25DV64K
act as a contactless
memory powered by the received carrier electromagnetic wave.
In I
2
C mode, the
ST25DV04K, ST25DV16K
and
ST25DV64K
user memory contains up to 512 bytes, 2048 bytes
and 8192 bytes, which could be split in 4 flexible and protectable areas.
In RF mode, following ISO/IEC 15693 or NFC forum type 5 recommendations,
ST25DV04K, ST25DV16K
and
ST25DV64K
user memory contains respectively up to 128 blocks, 512 blocks and 2048 blocks of 4 bytes which
could be split in 4 flexible and protectable areas.
ST25DV04K, ST25DV16K
and
ST25DV64K
offer a fast transfer mode between the RF and contact worlds, thanks
to a 256 bytes volatile buffer (also called Mailbox). In addition, the GPO pin of the
ST25DV04K, ST25DV16K
and
ST25DV64K
provide data informing the contact world about incoming events, like RF field detection, RF activity in
progress or mailbox message availability. An energy harvesting feature is also proposed when external conditions
make it possible.
Herein after all concerned devices (ST25DV04K,
ST25DV16K
and
ST25DV64K)
are mentioned as ST25DVxxx.

ST25DVxxx packaging
ST25DVxxx is provided in different packages:
•
8 pins (S08N or TSSPOP8 or UFDFPN8) for the open drain version of Interrupt output
•
10 balls (WLCSP) and 12 pins (UFDFPN12) for a CMOS interrupt output. This package includes an
additional element that minimizes standby consumption.
