1 / 54 page  1. General description The UCODE HSL IC, SL3ICS3001 (UCODE High frequency Smart Label) is a dedicated chip for passive smart tags and labels, especially for supply chain management and logistics applications in the US, where operating distances of several meters can be realized. Further, the UCODE HSL technology platform is also designed for operation under European regulations. This integrated circuit is the first member of a product family of smart label ICs targeted to be compliant with the future ISO standards 18000-4 and 18000-6 for item management. The UCODE HSL system offers the possibility of operating labels simultaneously in the field of the interrogator antenna (Anticollision, Collision Arbitration). The UCODE HSL family of ICs is especially designed for long range applications. The tag requires no internal power supply. Its contactless interface generates the power supply via the antenna circuit by propagative energy transmission from the interrogator (read/write device), while the system clock is generated by an on-board oscillator. The contactless interface demodulates data transmitted from the interrogator to the UCODE HSL based tag, and further modulates the electromagnetic field provided by the interrogator for data transmission from the UCODE HSL based tag to the interrogator. A generic RFID system consists of an interrogator (base station) that runs the RFID protocol, as well as one or more tags. The tag itself includes an SL3ICS3001 chip and an antenna tuned to the carrier frequency of the interrogator, and a package to hold the chip and antenna together. When placed in the RF field of an interrogator, a SL3ICS3001 based tag will begin to power up. If the field is strong enough, the tag IC will execute a power-on reset and will be ready to receive commands. Each command begins with a preamble and start delimiter that, taken together, enable the tag to perform clock and data recovery on the incoming signal. Data to and from the tag is checked for errors using a CRC. Therefore, CRC fields are present in all interrogator commands and in all tag responses. Additional data protection is provided by Manchester encoding on the forward (interrogator to tag) link and FM0 encoding on the return (tag to interrogator) link. The interrogator can perform a number of functions on tags in its field. For example, the interrogator can send a command sequence, which allows it to identify multiple tags in its RF field simultaneously. Alternatively, it can select a subset of the tags in the field based on tag memory contents. It can also read data stored on a tag in its field, as well as write data to such a tag. In addition, it can simultaneously write data to an arbitrary subset of the tags in the field. SL3ICS3001 UCODE HSL Rev. 3.1 — 9 July 2012 072831 Product data sheet COMPANY PUBLIC |
