Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. supplies ST25DV16KC-JF6D3 Dynamic NFC/RFID Tag IC with 16-Kbit EEPROM and Fast Transmission Mode Function

Description

The ST25DV16KC-JF6D3 device provides 16 Kbit electrically erasable programmable memory (EEPROM) for NFC RFID tags.The ST25DV16KC provides two interfaces. The first is an I2C serial link that can be operated from a DC power supply. The second is an RF link, which is activated when the ST25DV16KC is used as a contactless memory, which is powered by the received electromagnetic wave carrier.

All features

Data protection

User memory: 1 to 4 configurable areas, read and/or write protected by three 64-bit ciphers in RF and one 64-bit cipher in I2C

System configuration: write protection via 64-bit cipher in RF and 64-bit cipher in I2

GPO

Interrupt pins can be configured for multiple RF events (field change, memory write, active, end of fast transfer, user set/reset/pulse) and I2C events (memory write complete, RF switch off)

Open drain or CMOS output (version dependent)

RF management

RF command interpreter enabled/disabled via I2C host controller

I2C priority: immediately disconnect RF switch from I2C
