1 General description
The UHF EPCglobal Generation-2 standard allows the commercialized provision of
mass adoption of UHF RFID technology for passive smart tags and labels. Main fields
of applications are supply chain management and logistics for worldwide use with
special consideration of European, US and Chinese frequencies to ensure that operating
distances of several meters can be realized.
The NXP Semiconductors UCODE product family is compliant to this EPC Gen2
standard offering anti-collision and collision arbitration functionality. This allows a reader
to simultaneously operate multiple labels/tags within its antenna field.
The UCODE-based label/ tag requires no external power supply for contactless
operation. Its contactless interface generates the power supply via the antenna circuit by
propagative energy transmission from the interrogator (reader), while the system clock is
generated by an on-chip oscillator. Data transmitted from the interrogator to the label/tag
is demodulated by the interface, and it also modulates the interrogator's electromagnetic
field for data transmission from the label/tag to the interrogator.
A label/tag can be then operated without the need for line of sight or battery, as long as it
is connected to a dedicated antenna for the targeted frequency range. When the label/tag
is within the interrogator's operating range, the high-speed wireless interface allows data
transmission in both directions.
With the UCODE I2C product, NXP Semiconductors introduces now the possibility to
combine 2 independent UHF Interfaces (following EPC Gen2 standard) with an I2C
interface. Its large memory can be then read or write via both interfaces.
This I2C functionality enables the standard EPC Gen2 functionalities to be linked to an
electronic device microprocessor. By linking the rich functionalities of the EPC Gen2
standards to the Electronics world, the UCODE I2C product opens a whole new range of
application.
The I2C interface needs to be supplied externally and supports standard and fast I2C
modes. Its large memory is based on a field proven non-volatile memory technology
commonly used in high-quality automotive applications.
