ST25DV04K-IER8C3 Application Field and Working Principle

Introduction to ST25DV04K-IER8C3

ST25DV04K-IER8C3 is a leading RFID IC (Integrated Circuit) from STMicroelectronics. It is an NFC (Near Field Communication) & RFID tag, RF Access, Monitoring IC which is recognized for its read/write capability and high-speed data transfer. The ST25DV04K-IER8C3 is suitable for a wide range of application fields such as short distance wireless communication, anti-counterfeiting and consumer control in the intelligent identification, form & character recognition, automatic identification and location of goods, book & document management, or access control etc.

Features of ST25DV04K-IER8C3

The ST25DV04K-IER8C3 is a small form factor Solar Energy Harvesting Tag, based on the 13.56MHz ISM band and also is available in a variety of sizes, such as a small form factor size and contactless read/write capability. It supports Type A/B/F and ISO14443A & ISO14443B protocols. It also comes with a wide memory range up to 512Kbits (Kb) and a page size of 4K or 8K, suitable for a wide range of applications, with a low power consumption, high security, and low cost.

Product Applications

• NFC or RFID applications: the ST25DV04K-IER8C3 is suitable for NFC applications such as, but not limited to transport, asset tracking, or hospital patient identification.• Wireless RF communication: due to its ability of high-speed data transfer and read/write, the ST25DV04K-IER8C3 can be used in wireless communication, such as remote controls, key fobs, beacon tracking, or wireless payment.• Anti-counterfeiting: as the ST25DV04K-IER8C3 tag is based on the 13.56MHz ISM band, it also comes with an authentication with manufacturers\' chip ID and encryption and is thus suitable for anti-counterfeiting applications.• Security: due to its high memory range up to 512Kbits and the different security protocols, the ST25DV04K-IER8C3 tag is also suitable for security applications.

Working Principle of ST25DV04K-IER8C3

The ST25DV04K-IER8C3 comes with a read/write capability and provides a high-speed data transfer, up to 80 kbit/s. It achieves this by using a number of techniques, such as amplitude modulation which is used to increase the transfer rate. This technique is combined with modulation and coding to ensure that errors do not occur.The ST25DV04K-IER8C3 also comes with an array of security protocols, such as Type A/B/F and ISO14443A & ISO14443B protocols, which can be used to protect the data and prevent unauthorized access. Further, on-chip ROM usually stores the manufacturers\' chip ID and the data stored on the ST25DV04K-IER8C3 tag is also encrypted, which further helps to protect the contents from unauthorized access. The ST25DV04K-IER8C3 can also be used in Solar Energy Harvesting, as the tag comes with ultracapacitors of up to 42V. The solar energy from the ultracapacitors will be used to power the tag, thus increasing its power efficiency. This will reduce cost as solar energy is free.

Conclusion

The ST25DV04K-IER8C3 tag is an RFID IC from STMicroelectronics. It is an NFC & RFID tag, RF Access, and Monitoring IC, suitable for a wide range of application fields, such as anti-counterfeiting, security, wireless communication, and asset tracking. The ST25DV04K-IER8C3 provides a read/write capability with high-speed data transfer and comes with an array of security protocols to protect the data from unauthorized access. Furthermore, it is also available in a variety of sizes, with a low power consumption, high security, and low cost. The ST25DV04K-IER8C3 can also be used in Solar Energy Harvesting, as the tag comes with ultracapacitors of up to 42V, thus providing high performance and reducing cost.
