Datasheet - ST25DV04KC-IE8S3

The STMicroelectronics product is a NFC RFID tag that offers 4 Kbit of electrically erasable programmable memory EEPROM. The ST25DV04KC offers two interfaces. The first one is an I2C serial link and can be operated from a DC power supply. The second one is an RF link activated when the ST25DV04KC act as a contactless memory powered by the received carrier electromagnetic wave. In I2C mode user memories contain up to 512 bytes, which could be split in 4 flexible and protectable areas.

Single supply voltage is 1.8 V to 5.5 V

Multiple byte write programming

Configurable I²C slave address

NFC Forum Type 5 tag certified by the NFC Forum

Fast data transfer between I²C and RF interfaces

Half duplex 256 bytes dedicated buffer

Analog output pin to power external components
