UCODE® 7xm-1k, 7xm-2k and 7xm+
The UCODE 7xm series is the latest generation of NXP’s memory UHF tag ICs. With its read range, the UCODE 7xm is suited for applications which require high read range and also demanding an extended user memory to store data specific to customer or products. UCODE 7xm offers an user memory of 1-kbit, whereas UCODE 7xm+ supports 2-kbit user memory and a 384-bit digital signature.
Both products incorporate features known from UCODE 7 like pre-serialization, tag power indicator as well as the product status flag.
There are numbers of applications where the combination of high read range and user memory is needed, such as:
- Inventory and supply chain management
- Process optimization (e.g in the automotive industry)
- Brand protection/authentication (e.g. expensive wines or branded luxury fashion items)
- Automatic vehicle ID where no cryptography is required
- Asset tracking (e.g. for high value assets)

- High sensitivity enables smaller and cost efficient antenna designs
- Selected chip impedance enables re-use of antenna designs from UCODE 7
- 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
- Pre-serialization of the 96-bit EPC
- Fast encoding of the EPC content
- All mandatory commands of EPCglobal v1.2.0 specification are implemented
- The following optional commands are implemented:
- Access
- BlockPermalock (block size of 256-bit)
- 32-bit BlockWrite
- Implemented custom commands and features:
- Untraceable
- ReadSignature
- 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
