Microchip Technology, Inc. RFID, RF Access, Monitoring ICs ATA5575M1330-DDB

The ATA5575M1330-DDB is a contactless read/write identification IC designed for RFID applications operating in the 100 kHz to 150 kHz frequency range. It features a 128-bit EEPROM user memory, allowing for byte-wise read and write operations, and includes a unique data format for communication. The IC utilizes load modulation for uplink data transmission and is optimized for maximum read range, although the write range is limited. This device is equipped with an on-chip trimmed antenna capacitor and supports various configurations, including direct access mode and one-time programmable (OTP) functionality. The chip is designed for access control applications and includes built-in options for high Q-antenna tolerance. The ATA5575M1330-DDB is delivered as a die on a sawn wafer with a thickness of 150 µm, making it suitable for integration into various RFID systems.
