1 PRODUCT DESCRIPTION
The Axxin Kinetic RFID Reader (Axxin P.N. P002264) is a compact HF RFID reader module
with integrated antenna, crystal and a flexible SPI based interface with external microcontroller.
The module is to be fitted primarily (but not exclusively) into Axxin design products.
The module is based on an industry standard Texas Instruments TRF7960 silicon (fully
integrated, multi-standard HF 13.56MHz, reader system) and supports ISO15693 standard
RFID Tags, optionally ISO14443A and ISO14443B Tags support may be implemented if
required (additional EMC and RF tests and certification may be required in such cases).
The module requires external microcontroller for operation and initialization using simple SPI
and GPIO based interface.
This manual includes a list of Axxin RFID module features, a brief description of the module,
specifications, details on instruction for configuration and integration.
Please note that the module is designed and meant to be used as a standard configuration of
TRF7960 silicon based ‘RFID Front End’ and therefore it’s not the purpose of this manual to
provide a fully comprehensive description of module functionality and features as they are
included in TRF7960 silicon related documentation, which should be used for the purpose of
module integration into equipment.

3.2 INTERFACE SIGNALS LEVELS
Interface signals between Axxin Kinetic RFID Reader module and equipment can be divided
into 3 categories:
1. SPI interface signals (SPI_CS, SPI_CLK, SPI_MISO, SPI_MOSI) are 3.3V Logic level
(please refer to SPI interface standard and TRF7960 data sheet for details)
2. Control signals (TRF7960_EN, Direct Mode, Module RFID, IRQ) are 3.3V logic level.
3. Power Supply Rails (3.3V, 5V), refer to current voltage requirements listed elsewhere in
this manual.
3.3 METALS IN PROXIMITY AND EFFECT ON ANTENNA
Please note that metallic object in close proximity of Reader Module can affect the reading
distance, in severe situations additional antenna tuning may be required.
3.4 READING DISTANCE
Typical expected Tag reading distance from module’s antenna is around 40 -50mm.
The distance will be affected by shape and size of used Tag, proximity of metallic objects, Tag
position with respect to antenna etc…
3.5 POWER RAILS REQUIREMENTS
Axxin Kinetic RFID Reader module is powered by 5V DC and 3.3V DC. The power supply
specifications must meet the requirements in Table 2.1 and Table 2.2
3.6 CONTROLLER REQUIREMENTS
Axxin Kinetic RFID Reader module requires external microcontroller for both initialization and
functionality.
Interface between Reader module and external microcontroller consist of a standard 4 wire SPI
interface (with CS) and 4 GPIO signals and should meet the following requirements:
3.3V logic level GPIO
SPI interface with SS, for details please refer to TRF7960 Data sheet (SLou186E), Page
39-42.
3.7 MECHANICAL SUPPORT
RFID module should be supported mechanically by using preferably non-metallic bracket.
This ensures fixed position of the antenna, proper electrical interface connections and
mechanical reliability of the assembly.

interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
