1. General description
The UCODE 7xm series is the latest generation of NXP’s memory UHF tag ICs. With the
leading-edge read range UCODE 7xm is well 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 or 2-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)

UCODE 7xm and UCODE 7xm+
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
UCODE 7xm can be used in combination with readers compliant with EPCglobal v1.2.0
standard. For access to full UCODE 7xm family functionality firmware upgrade of the
reader may be necessary.

5. Block diagram
The UCODE 7xm/7xm+ consists of three major blocks:
- Analog Interface
- Digital Control
- EEPROM
The analog part provides stable supply voltage and demodulates data received from the
reader which is then processed by the digital part. Further, the modulation transistor of the
analog part transmits data back to the reader.
The digital control includes the state machines, processes the protocol and handles
communication with the EEPROM, which contains the EPC and the user data.
