The ATA556714N-DDB is a popular radio-frequency identification, or RFID, IC developed by Atmel. It is part of a family of RF access, monitoring ICs designed for applications ranging from access control to asset tracking. The DDB version of the Atmel IC is a dual-bank chip that provides increased memory capacity, allowing for secure data storage and faster data transfer. The chip is typically used in devices such as smart cards, tokens, tags, and RFID readers.

The ATA556714N-DDB is capable of operating on a standard RFID 13.56MHz frequency. The chip features 433 bits of EEPROM non-volatile memory divided into two banks which can be programmed with different passwords and access levels for secure access control applications. The chip also includes an anti-tamper mechanism that triggers a security event when an unauthorized attempt is detected. This makes the ATA556714N-DDB well-suited for applications where secure access is necessary.

Atmel’s ATA556714N-DDB IC combines advanced encoding technology for improved accuracy and data reliability. The chip implements Manchester coding to provide a high-resolution read capability from up to 20 tags at a time. The chip is capable of detecting multiple tags simultaneously and can correctly identify tags with similar ID numbers. The chip also features an integrated digital signal processor (DSP) which performs the signal processing operations necessary for reliable operation. The processor is coupled with a powerful SDRAM, allowing for fast data transfers at high speeds.

The ATA556714N-DDB also features a low-power, low-energy consumption design for extended battery lifetimes. The chip is capable of operating in dynamic tag orientations and features a unique wake-up mechanism that reduces power consumption when in inactive states. An integrated CPU performs the necessary housekeeping operations for the chip and provides clock and data signals for the chip functions.

Atmel’s ATA556714N-DDB is ideal for applications where secure data storage and accurate data transfer are essential. The chip provides a low-energy, low-power design for extended battery life and is capable of reading multiple tags at once. The integrated DSP and SDRAM provide fast data transfers and the anti-tamper mechanism adds an extra layer of security. Windows and Linux compatible development tools are available to help developers get started with their projects.
