NFC1-Module
Integration Manual V1.01
The NFC1 module is targeted as an RFID-Reader and NFC-Device for integration into different Fronius products.
A typical application of RFID is user authentication. Selling the single module directly to customers is not permitted.
It consists of two parts – the printed circuit board with the transmitter IC and the Flex-PCB loop antenna.
The circuit board of the module is designed to be soldered directly on to a host board, as shown below:

Definition:
RFID (Radio-frequency identification):
is the wireless use of electrom agnetic fields to transfer data, for the purposes of autom atically identifying and
tracking tags attached to o bject s. T he tags conta in ele ctronic ally stored inform ation. Som e tags are p owered by
electromagnetic induction from magnetic fields produced near the reader.

NFC (Near field communication):
is a set of ideas and technol ogies that en able sm art phones and ot her devices to establish radio com m unication
with each other by touching them together or bringing them into prox imit y, typically a distance of 10 cm (3.9 in)
or less. Each full NFC device can work in 3 modes: NFC target (acting like a credential), NFC initiator (as a reader)
and NFC peer to peer.

Module Description:
Antenna:
The antenna is part of the module and connected to the printed circuit board using a unique connector.
Its coil consists of 5 turns which have been integrated on a flexible printed circuit board.
The size of the antenna coil is 64 x 39mm.
Printed circuit board:
The printed circuit board of the module consists of three block s: The transmitter IC, the analog circuit for the
antenna and the quartz oscillator.

Transmitter IC:
Heart of the module is the transmitter IC. The transmitter IC is a full featured NFC controller. It builds a contactless
front-end supporting various communication modes at different transfer speeds and modulation schemes.
The transmitter IC can be connected on a host controller through the serial interface.
An integrated CPU is decoupling the host controller from the timing constraints of RF communication and allowing
autonomous operation.
Moreover, the transmitter IC provides an integrated power regulation unit.
A TX-overcurrent protection is shutting down the transmitter stage if a overcurrent happens.
Analog circuit:
The analog circuit contains all relevant components required to connect the antenna to the transmitter IC. It also
ensures the transmiss ion of energy and data to the target device as well as the reception of a target device
answer.
Frequency generation:
A 27.12 MHz quartz oscillator is connected to the transmitter IC. It is the time reference for the RF front-end when
the module is beh avin g in r eader m ode or ISO/IEC 18092 initiator as well as in t arget when conf igured i n activ e
communication mode.
Host connection:
Host connection is realized b y a digital serial interfac e. Data inputs on the m odule are buffered (HT80C51 MX
processor in the transmitter IC).
Host interface supply (PVDD):
The interface part of the NFC1-Module must be supplied between 1.65V and 1.95V.
PVDD is buffered by a capacitor on the module.
Module supply and power regulation:
The NFC1 module must be supplied between 2.85V DC and 5.5V DC
VBAT is buffered by a capacitor on the module.
The module has a built-in power regulator (PMU). The part number of the power regulator is U1 (integrated inside
the transmitter IC) which generates internal supplies required by the IC out of the VBAT supply:
/ DVDD: Digital supply (buffered by capacitor)
/ AVDD: Analog supply (buffered by capacit o r)
/ TVDD: Supply for RF transmitter (buffered by capacitor)

Operational description:
The circuit board of the module will be soldered directly on to a host board where it will be connected to the host
processor through the serial interface. The host board also has to provide the power supply of the module.
After powering up or resetting by the module it has no autonomous function and the transmitter stage is
deactivated.
A setup procedure has to b e performed through the serial interf ace to set u p the pollin g loop conf iguration and
enable the single reader technologies.
Polling Loop:
After the setup procedure the m odule is in a polling lo op wh at m eans the m odule polls for RFID/NFC targets off
all enabled technologies. Regular after finishing a loop cycle a pause time is inserted and the rf-field is turned off
(pause time). During this time the module is in card emulation / passive target mode.
Every single technology can be enabled / disabled individually, pause time can be configured.
The module stays inf initely in this loop until a reset from the user is received or a target is detected (placed into
the field). A target can be a RFID transponder card (e.g. Mifare) or an NFC enabled device (not part of the EUT).
As soon a target is in the field the mo dule stays in the technology of the current target and inform s the host
controller that a target is acquired. Now the host controller can perform some read / write operations on the target.
Then it release it and restarts the polling loop.
Some targets allow higher baudrates. After target regis tration the highest allowed baudrate can be configur ed
during the target activation procedure. The transmitter IC is changing to the highest allowed and supported
baudrate automatically.

Labeling
Using a permanently affixed label, the modular transmitter will be labeled with its own FCC
identification number, and, if the FCC identification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. The same applies to the IC (Industry Canada)
identification number.
This exterior label can use wording such as the following:
For the USA:
“Contains FCC ID QKWNFC1”
Any similar wording that expresses the same meaning may be used.
For Canada:
“Contains IC: 12270A-NFC1”
Any similar wording that expresses the same meaning may be used.
