RF Identification (RFID) Products

Sensitive, Low-Power RF Identification Devices 

RFID is a contactless technology that involves using an RF signal to read and write data into an RFID tag's nonvolatile memory. Low-frequency RFID devices typically consist of a transponder (tag) and a reader.

To help you design solutions for the many vertical markets that rely on RFID technology, we offer a variety of contactless read or read/write products. Our transponders operate within the 100 to 150 kHz bandwidth range. Our RFID chips are suitable for the smallest devices and don’t require any external components, which reduces the cost of your tag.

These identification ICs are available as die-on-wafers with optional gold bumps, packaged die or an entire transponder.

RFID Products

Simplify the Production Process and Accelerate Time to Market

Our low-frequency Identification IC (IDIC) devices are designed for the latest generation of contactless access control systems used in hotel room, office and parking lot applications as well as customer loyalty and membership cards. Their One-Time Programmable (OTP) functionality simplifies the production process and accelerates time to market.

Device Description
ATA5575M1 Low-frequency read/write identification IC with OTP functionality that targets general consumer and industrial RFID applications using a 64-bit unique ID
ATA5575M2 Low-frequency read/write identification IC with OTP functionality that targets ISO 11784 and ISO 11785 RFID applications in FDX-A and FDX-B modes that are used for animal identification

Integrate Components to Reduce Your Bill of Materials

Our low-frequency Identification IC (IDIC) devices integrate components to reduce your bill of materials. A single coil connected to the chip serves as the power supply and bi-directional communication interface, while the antenna and chip together form the transponder (tag). An on-chip EEPROM can be read and written block-wise from the reader.

Device Description
ATA5577M1C

Low-frequency read/write identification IC for applications in the 125 kHz or 134 kHz frequency band

 
ATA5577M2C

Low-frequency read/write identification IC with gold-bumped mega pads for applications in the 125 kHz or 134 kHz frequency band
