UCODE 7m is a derivative of the UCODE 7 and offers on top of the UCODE 7 features a32-bit User Memory.

NXP’s UCODE 7m IC is the leading-edge EPC Gen2 RFID chip that offers best-in-classperformance and features for use in the most demanding RFID tagging applications.

Particularly well suited for inventory management application, like e.g Retail and Fashion,with its leading edge RF performance for any given form factor, UCODE 7m enables longread distance and fast inventory of dense RFID tag population. With its broadband design,it offers the possibility to manufacture true global RFID label with best-in-classperformance over worldwide regulations.

The device also provides an automatic self pre-serialization feature for 96-bit EPC,following the industry aligned Multi Vendor Chip-based serialization scheme, and aParallel encoding feature. For applications where the same 58-bit Stock Keeping Unit(SKU) needs to be encoded on multiple tags, at the same time, a combination of bothfeatures improves and simplifies the tag initialization process.

On top UCODE 7m offers a Tag Power Indicator for RFID tag initialization optimizationand a Product Status Flag for Electronic Article Surveillance (EAS) application.

Key features

Memory

• 32-bit User Memory
• Up to 128-bit of EPC memory
• Supports self pre-serialization for 96-bit EPC
• 96-bit Tag IDentifier (TID) factory locked
• 48-bit unique serial number factory-encoded into TID
• 32-bit access password
• Wide operating temperature range: ?40 °C up to +85 °C
• Minimum 100.000 write cycle endurance

End user benefits

• Long READ and WRITE ranges due to leading edge chip sensitivity
• Very fast bulk encoding
• Product identification through unalterable extended TID range, including a48-bit serial number
• Reliable operation in dense reader and noisy environments through highinterference rejection

Antenna design benefits

• High sensitivity enables smaller and cost efficient antenna designs for thesame retail category
• Tag Power Indicator features enables very high density of inlay on rollswithout crosstalk issues during writing/encoding
• The different input capacitance for the single slit antenna solution enablesa finer tuning of the impedance for the antenna design

Label manufacturer benefits

• Large RF pad-to-pad distance to ease antenna design
• Symmetric RF inputs are less sensitive to process variation
• Single slit antenna for a more mechanically stable antenna connection
• Automatic self pre-serialization of the 96-bit EPC anytime its EPC serialnumber is erased
• Extremely fast encoding of the EPC content

Supported features

• All mandatory commands of EPC global specification V.1.2.0 are implementedincluding:
  • (Perma)LOCK
• The following optional commands are implemented in conformance with the EPCspecification:
  • Access
  • BlockWrite (2 words, 32-bit)
• Product Status Flag bit: enables the UHF RFID tag to be used as EAS(Electronic Article Surveillance) tag without the need for a back-end database.
• Tag Power Indicator: enables the reader to select only ICs/tags that haveenough power to be written to.
• Parallel encoding: allows for the ability to bring (multiple) tag(s) quicklyto the OPEN state and hence allowing single tags to be identified simply,without timing restrictions, or multiple tags to be e.g. written to at thesame time, considerably reducing the encoding process

All supported features of UCODE 7m can be activated using standard EPCglobal READ /WRITE / ACCESS / SELECT commands. No custom commands are needed to takeadvantage of all the features in case of unlocked EPC memory. The parallel encodingfeature may however require a firmware upgrade of the reader to use its full potential.
