Low frequency RFID IC with OTP functionality for access control systems

Atmel has launched the ATA5575M1, a new LF OTP (One Time Programmable) transponder RFID IC member of Atmel's RFID transponder family optimized for access control systems. The ATA5575M1 simplifies the production process and provides flexibility compared to read-only devices. Customers can program the required code before shipping.

The ATA5575M1's architecture enhances read distances with different types of coils and readers. The write distance has been reduced since a short write distance is sufficient and safer, which minimizes the cost and chip size. The ATA5575M1 measures about 0.9 square millimeters, the chip can be used in any transponder package, including glass transponders for small tags such as plastic key housings.

A unique ID is vital for access to secured areas and enabling traceability of the end product. The ATA5575M1's user memory contains a unique, manufacturer-programmed ID. In standard applications, the system designer can simply lock the tag and use this pre-programmed unique ID as is. In applications requiring an individual, unique ID, the designer can overwrite the existing ID by using the desired customer-specific code.

The ATA5575M1 device is insensitive to rugged environments and can also be used under conditions that normally complicate the application of RFID devices such as under water, on metal, in dirt, out-of-sight, or worn on the body.

The ATA5575M1 transponder IC supports ASK modulation and Manchester coding with a fixed bit rate of RF/64 and is designed for passive identification systems with a 100 to 150 kHz magnetic field.
