Descriptive summary

UCODE 7xm and 7xm+

NXP's UCODE 7xm and 7xm+ are the newest generation of UCODE products, designed for applications which require extended memory. UCODE 7xm / 7xm+ support 1 kbit / 2 kbit of User memory and 448 bit EPC memory. Both devices support the untraceable feature on top of the well-known features of UCODE 7, such as Automatic self pre-serialization of the EPC, Parallel Encoding, Product Status Flag and Tag Power Indicator. For product authentication applications UCODE 7xm+ incorporates a Digital Signature based on a public key algorithm.

UCODE 7m

NXP’s UCODE 7m is the latest product of UCODE 7 NXP transponder IC series and offers a 32 bit user memory. UCODE 7m provides the same read and write performance as UCODE 7 and therefore also enables the design of global versatile RFID labels that fit to the requirements of the retail industry. The new UCODE 7m is EPC Gen2 compliant and comes with the same features supported by UCODE 7 such as Automatic self pre-serialization of the EPC, Parallel Encoding, Product Status Flag and Tag Power Indicator.

UCODE 7

Our UCODE 7 IC EPC Gen2 RFID chip offers best-in-class performance and features for the most demanding RFID tagging applications. With its leading edge RF performance for any given form factor, UCODE 7 enables long read distance and fast inventory of dense RFID tag population. UCODE 7 chip design enables manufacturing of global RFID labels with best-in-class performance over worldwide regulations. The device provides an automatic self pre-serialization feature for 96-bit EPC, following the industry aligned Multi Vendor Chip-based serialization scheme (MCS), and a Parallel encoding feature which improves and simplifies the tag initialization process. UCODE 7 also offers a Tag Power Indicator for RFID tag initialization optimization and a Product Status Flag for Electronic Article Surveillance (EAS) application.

UCODE G2iM and G2iM+

NXP's UCODE G2iM series transponder ICs are the newest generation of UCODE products for use in applications where additional memory is required. In addition to the leading-edge read range and the 640 bit configurable user memory, UCODE G2iM offers features like read protect, block write and integrated Product Status Flag (PSF). UCODE G2iM+ also features an integrated tag tamper alarm, digital switch, external supply mode, data transfer mode and the conditional, automatic real read range reduction. This is where the activation condition can be defined by the user. In the UCODE G2iM+ the 640 bit user memory can be segmented or configured so that EPC memory up to 448 bit can be supported.

UCODE G2iL and G2iL+

With its industry-leading single port read range allowing simple antenna designs, the UCODE G2iL series is ideal for cost-effective RFID applications. UCODE G2iL+ offers industry-first special features such as tag tamper alarm, digital switch, data transfer, read protect, real read range reduction and battery assist mode.

UCODE G2XM and UCODE G2XL

These ICs help keep track of your products throughout manufacturing. Passive RFID chip solutions make pallet-, case- and item-level tracking reliable and cost-effective, helping to stop counterfeiting while speeding up inventory counting. A unique password-protected custom command set includes EAS for increased theft protection, a read protect feature to prevent unauthorized memory access and calibration, allowing optimization of the reader-to-tag communic The ICs are EPCglobal C1G2 1.0.9 certified and compliant to EPCglobal C1G2 1.1.0. They provide unsurpassed UHF performance with reliable operation in dense reader domains and over long read ranges. They feature an extended, 240 bit EPC number and 64 bit tag identifier. Plus, UCODE G2XM provides a 512 bit on-chip dedicated user memory.

UCODE HSL (High frequency Smart Label)

The SL3 ICS3001 is a dedicated chip for passive, intelligent tags and labels. Its RF interface allows high-speed bi-directional data transmission, while the advanced anti-collision and collision arbitration techniques allow writing to/reading from multiple labels simultaneously. UCODE HSL offers 216 bytes of user memory and a 64 bit unique identifier.

UCODE DNA

UCODE DNA is the world's first UHF (ultra-high frequency) RAIN RFID tag IC to combine long-range read performance with cryptographic authentication. With this new tag IC developers no longer have to choose between contactless performance and the need for security in their applications; UCODE DNA enables them to have access to both in a single RAIN RFID tag IC. The new tag IC is ideal for use in a wide variety of applications, such as electronic road tolling, electronic vehicle registration, license plate authentication, access control, asset tracking, brand protection, parking, and fast visitor processing and special service offering at large scale venues, sports stadiums or entertainment parks.
