STMicroelectronics (Korea Country Representative: Jun-Sik Park) is expected to help increase productivity and efficiency in industrial applications such as smart meters, asset tracking, and logistics through the launch of a dual-interface NFC tag with enhanced performance for fast and easy access to internal EEPROM memory.

STMicroelectronics (hereinafter ST), a global semiconductor company supporting customers with a variety of electronic applications, announced on the 7th that it recently launched the new ST25DV-I2C.

ST25DV-I2C is ST's dynamic I2C tag that enhances performance to enable host systems to quickly and easily access the EEPROM memory within the ST25DV-I2C (hereinafter ST25DV).

The EEPROM writing function of the new ST25DV tag via the I2C interface is capable of processing as fast as standard EEPROM.

Through this, it is possible to expect the effect of reducing the system's Bill of Materials (BOM) by using NFC dynamic tags in EEPROM use cases.

In other words, in applications using ST25DV, there is no need to configure an additional EEPROM for memory storage purposes with data processing speed in mind. In addition, the tag's I2C address can also be configured so that a single I2C bus can be shared with other devices.

The NFC Forum Type-5 NFC tag ST25DV supports contactless communication with 13.56MHz RFID readers and NFC phones.

Representative application examples of ST25DV include communication methods using NDEF (NFC Data Exchange Format) messages and pairing connections using tabs.

In addition, this new tag allows you to conveniently retrieve information within the tag via the NFC RF interface.

The latest version of the ST25DV leverages enhanced performance and flexibility to help increase productivity and efficiency in industrial applications such as smart metering, asset tracking, and logistics.

It also provides an excellent user experience in medical equipment, smart home devices, lighting, smart retail labels, and consumer products.

The ST25DV tag assists with product configuration, product tracking (e.g., production lot number, production date, etc.), user features, field maintenance, and end-of-life management.

This new tag also supports Fast Transfer Mode and energy harvesting. ST's Fast Transfer Mode utilizes a 256-byte buffer to rapidly process large files, such as firmware updates for host systems. The integrated circuit controlling energy harvesting can be designed to supply power in battery-free applications. By utilizing this feature, firmware update rework for shipped products can be facilitated, and through this, cost savings on rework on the production line can be expected.

The ST25DV dynamic tag complies with the NFC Forum Type-5 specification and includes an EEPROM with a maximum capacity of 64Kbit. Additionally, it provides password protection to safeguard information stored in the EEPROM memory. Furthermore, it offers a programmable interrupt pin to respond to various events detected by the RF interface.

The enhanced ST25DV-I2C tag is available in chip-scale packages including SO-8 and TSSOP-8, as well as 8-lead UFDFPN, 12-lead UFDFPN, and WLCSP-10 (10 pins). The ST25DV-I2C series dynamic tags are currently available for free samples, and pricing starts at $0.33 for a 4Kbit EEPROM SO8 package purchase of 1,000 units on ST's eStore.
