UCODE I2C RFID Chip

NXP Semiconductors'UCODE I2Cchip has an integrated I2C interface and a 3,328-bit user memory. The UCODE I2CIC brings the power of Gen2 UHF to embedded systems, enabling bidirectionalcommunication between a wireless reader and a microprocessor via an I2C bus.Using UCODE I2C, electronic devices can be configured and customized remotely,enabling wireless data exchange and product provisioning even while the deviceis powered down.

The UCODE I2C IC has 3,328 bits of EEPROMmemory, which can be used to upload updates to the embedded microprocessor uponpower up. The UHF interface includes two independent front-ends, each of whichcan be enabled or disabled independently, as well as an RF or I2C interfacewhich can also be disabled independently.

The UCODE I2C functionality can be used indifferent ways. As an anti-theft measure, electronic devices moving throughsupply chain can remain disabled until they have been provisioned remotelythrough the I2C bus, and each device can be tracked through a unique tag ID(TID). The UCODE I2C chip enables retailers to pre-configure and customize itwithout opening the box and pre-loading customer account information. UCODE I2Ccan remotely deliver minor upgrades or enable optional features. In the eventof any problems, UCODE I2C makes it possible to identify the serial number aswell as the error logs internal to the device without opening it.

Other target applications include RFID dataloggers and sensors for products such as perishable foods and pharmaceuticals.By passing sensor information through the I2C bus, the UCODE I2C IC can track,monitor and record information such as temperature, humidity, pressure andshock as the products move through the supply chain.
