Atmel Corporation RFID, RF Access, Monitoring ICs ATA555711-TASY

The ATA555711-TASY is a contactless read/write identification integrated circuit (IC) designed for RFID applications operating in the 125 kHz frequency range. It features a 330-bit EEPROM memory, which is organized into 10 blocks, allowing for block-wise read and write operations. The IC supports various modulation and coding schemes, including FSK, PSK, Manchester, Biphase, and NRZ, and offers configurable data rates from RF/2 to RF/128. This IC is compatible with ISO/IEC 11784/785 standards and includes a password protection feature to prevent unauthorized access. It also supports multiple operational modes, such as Answer-On-Request (AOR) and direct access mode. The device is designed to operate with a single coil that serves both as a power supply and a communication interface, making it suitable for applications in access control and monitoring systems. The ATA555711-TASY is available in an 8-SOIC package, which is lead-free.
