SL3S4011/4021: UCODE I²C
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 gen 2 standard) with an I²C interface. Its large memory can be then read or write via both interfaces.
This I²C functionality enables the standard EPC gen 2 functionalities to be linked to an electronic device microprocessor. By linking the rich functionalities of the EPC gen 2 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.
