SL3S4021FHK

The SL3S4021FHK is an UCODE I²C RF IC for use with theft protection and deterrence. 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.
