RFID has seen widespread deployment across various industries ranging from logistics to security. With the advent of contactless RFID technology, the range of possible applications has expanded to include access control, asset tracking and identity verification. With this in mind, Atmel has released the ATA556711-TAQY, a monitoring IC designed to meet the needs of modern RFID applications. This article will provide an overview of the ATA556711-TAQY’s application field and working principle.

The Application Field of ATA556711-TAQY

The ATA556711-TAQY is designed specifically for applications where RFID tag monitoring and access control are required. It incorporates an integrated transponder interface, allowing it to read and write data to and from ISO/IEC18000-6B tags. The chip also supports anti-collision protocols, allowing multiple tags to be read simultaneously with minimal power consumption. The ATA556711-TAQY is suitable for both contactless and contact-based applications, with support for multiple reader modes including low-frequency, high-frequency and NFC.

In addition to RFID tag monitoring and access control, the chip can also be used for more general applications such as remote monitoring and asset tracking. It is capable of detecting motion and temperature changes in its vicinity, and can be used to detect tampering and suspicious activity. The combination of these features makes it suitable for a variety of applications from industrial automation to smart homes.

Working Principle of ATA556711-TAQY

The ATA556711-TAQY operates by sending and receiving data over an RFID interface. Data is sent using the ISO/IEC 18000-6B protocol, and is encoded using Manchester coding. The chip supports anti-collision protocols, allowing multiple tags to be scanned simultaneously while minimizing power consumption. The chip is powered by a 3.1-5.25V power supply and runs at a clock speed of 12.5MHz.

The chip is designed to operate in three distinct modes – Read, Write, and Idle. In Read mode, the chip scans for compatible tags and reads the data stored on them. In Write mode, the chip writes data to compatible tags, overwriting any existing data. In Idle mode, the chip does nothing but wait for an RF signal.

The chip is also capable of monitoring environmental conditions such as temperature and motion. This is done by measuring changes in the frequency of the RF signal. The chip uses this data to determine if anything has changed in its vicinity without having to scan for tags. This can be used to detect tampering or suspicious activity.

Conclusion

The Atmel ATA556711-TAQY is a monitoring IC designed for RFID tag monitoring and access control applications. It incorporates an integrated transponder interface, allowing it to read and write data to and from compatible tags. The chip also supports anti-collision protocols, allowing multiple tags to be scanned simultaneously while minimizing power consumption. Finally, the chip is capable of monitoring environmental conditions such as motion and temperature, allowing it to detect tampering and suspicious activity.
