描述 Description

UCODE? 7m is a derivative of the UCODE 7 and offers on top of the UCODE 7 features a 32-bit User Memory.

NXP’s UCODE 7m IC is the leading-edge EPC Gen2 RFID chip that offers best-in-class performance 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 long read 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-class performance over worldwide regulations.

The device also provides a pre-serialized 96-bit EPC, and a Parallel 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 both features improves and simplifies the tag initialization process.

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

Key benefits
End user benefit

Long READ and WRITE ranges due to leading edge chip sensitivity

Very fast bulk encoding

Product identification through unalterable extended TID range, including a 48-bit serial number

Reliable operation in dense reader and noisy environments through high interference rejection


Antenna design benefits

High sensitivity enables smaller and cost efficient antenna designs for the same retail category

Tag Power Indicator features enables very high density of inlay on rolls without crosstalk issues during writing/encoding

The different input capacitance for the single slit antenna solution enables a finer tuning of the impedance for the antenna design


Label manufacturer benefit

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 serial number is erased

Extremely fast encoding of the EPC content


Supported features

All mandatory commands of EPC global specification V.1.2.0 are implemented including:
\t
\t(Perma)LOCK

\t


The following optional commands are implemented in conformance with the EPC specification:
\t
\tAccess

\tBlockWrite (2 words, 32-bit)

\t


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 data base.

Tag Power Indicator: enables the reader to select only ICs/tags that have enough power to be written to.

Parallel encoding: allows for the ability to bring (multiple) tag(s) quickly to 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 the same 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 take advantage of all the features in case of unlocked EPC memory. The parallel encoding feature may however require a firmware upgrade of the reader to use its full potential.
