NXP Semiconductors has introduced its latest UHF RFID solutions for the fashion, retail and electronics markets.
The UCODE G2iL and G2iL+ enable leading-edge read ranges based on a simple, cost-effective single antenna solution. In addition, the new chips offer a tag tamper alarm, several privacy mode options and password protected data transfer or digital switch.
The chips offer a single antenna port sensitivity of -18 dBm, requiring only half the RF power to activate the chip compared to previous UCODE devices. This results in long read ranges which match dual antenna port solutions with equal sized antennas. The UCODE G2iL+ further improves both read and write performance to -23 dBm when connected to a power supply.
The UCODE G2iL series offers a product status flag which can be set and reset repeatedly to indicate whether a product has undergone a quality check or passed a certain process checkpoint, and can also be used as an electronic article surveillance (EAS) alarm. Privacy protection is available in a number of different ways, including the read protect feature, which allows the RFID chip to deny general access to product information contained in its EPC/TID memory, and allow authorised access only. The read protect feature can be set and reset repeatedly, using 32-bit password protection.
The UCODE G2iL+ boasts several features over and above those of the UCODE G2iL. While conventional RFID tags can easily be removed, the UCODE G2iL+ includes a tag tamper alarm feature which detects any attempts to tamper in case a label is ripped, torn or moved. This unique tag tamper feature sends a signal to the reader that it has been manipulated.
Enabling flexible product configuration and activation at any stage including the point of sale (POS), a digital transfer digital switch feature is specifically tailored to reduce theft and manage inventory levels in the electronic device market. Firmware or configuration data can be loaded into the microcontroller of a device via the air interface of the UCODE G2iL+ chip, allowing device manufacturers to enable or disable specific features for different device models, or lock and unlock the device at various control points along the supply chain or at the final point of sale. The UCODE G2iL+ also offers a real read range reduction, which reduces the read range to only a few inches, so that both consumers and shop owners don’t need to worry about unauthorised reads.
