It is designed for compact, low-cost contactless cards applications such as access control, asset tracking, and RFID tags. It supports a range of working frequencies from 106 kHz to 134.2 kHz, and is designed to perform full duplex communication with 13.56 MHz radio frequency. The device integrates antenna interface voltage regulator, microcontroller, memory, and RF management circuits into a single layer package with a power consumption of 17mA at 125 KHz.

Application Field

The ATA555812C-DDB is a versatile device and can be used in a variety of applications. It is a great option for access control, asset tracking, and contactless payment systems. It is also ideal for biomedical, identification cards, door access, and identification systems. Furthermore, the device can be used in automotive applications, such as car immobilizers, remote keyless entry, and secure authentication. Additionally, it can be used in radio frequency readers and secure messaging systems.

Working Principle

The ATA555812C-DDB works using near field communication (NFC) technology. It operates in a 13.56MHz frequency band, allowing it to perform full duplex communication with a range of connected RF devices. The device has a operating frequency of 106 KHz to 134.2 KHz depending on the type of card in use. It is normally powered by a single 3V supply but can be used in a range of applications. The device works by using a radio frequency signal to identify and authenticate a card. When a card is read, it is identified using a unique ID code. The ATA555812C-DDB has a built-in memory that stores all the necessary information about the card, such as a valid access code, until it is cleared from the device. The device also uses an enhanced access control algorithm that ensures only authorized users have access to a device or location. The access algorithm provides triple data encryption, using DES, 3DES, and AES encryption methods. All access operations are logged and stored securely in the device\'s internal memory, and the logs can be accessed remotely at a later date for further analysis.

Conclusion

The ATA555812C-DDB is a powerful device that can be used in a variety of applications. It has a wide range of working frequencies, can perform full duplex communication, and has a built-in memory for storing data. The device also features an enhanced access control algorithm to ensure only authorized users have access to a device or location. This makes it an ideal choice for access control, asset tracking, and contactless payment systems.
