FCC User Information
Statement according to FCC part 15.19:
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) this device must accept any interference received, including interference that may cause undesired operation.
Statement according to FCC part 15.21:
Modifications not expressly approved by this company could void the
user's authority to operate the equipment.
RF exposure mobil:
If using a permanently affixed label, the modular transmitter must 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. This exterior
label can use wording such as the following: “Contains Transmitter Module
FCC ID: SIFNANOLOCAVR0108” or “Contains FCC ID:
SIFNANOLOCAVR0108.” Any similar wording that expresses the same
meaning may be used.
so. In aircraft, use of any radio frequency devices must be in accordance
with applicable regulations. Hospitals or health care facilities may be
using equipment that is sensitive to external RF energy.
With medical devices, maintain a minimum separation of 15 cm (6
inches) between pacemakers and wireless devices and some wireless
radios may interfere with some hearing aids. If other personal medical
devices are being used in the vicinity of wireless devices, ensure that the
device has been adequately shielded from RF energy. In a domestic
environment this product may cause radio interference in which case the
user may be required to take adequate measures.
CAUTION! Electrostatic Sensitive Device. Precaution should be used when handling the
device in order to prevent permanent damage.
Statement according to FCC part 15.105:
This equipment has been tested and found to comply with the limits for a
Class A and Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation and against harmful interference
when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions as provided in the user manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required
to correct the interference at his or her own expense.
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 or more 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
connected.
•Consult the dealer or an experienced technician for help.
This smart nanoLOC AVR Module is only 35 mm by 14 mm and less than 3 mm thick. Yet it integrates all the required components for a complete RF module based on Nanotron’s innovative
nanoLOC TRX Transceiver. As well as the nanoLOC chip, this module includes the Atmel AVR
ATmega644V microcontroller, a band pass filter, a balun, and an integrated 2.4 GHz chip antenna.

1.1Certification
The nanoLOC AVR Module has been certified for use in Europe (R&TTE), Japan (ARIB-T66), and
the United States (FCC).
nanoLOC supports a freely adjustable center frequency with 3 non-overlapping frequency channels within the 2.4 GHz ISM band. This provides support for multiple
physically independent networks and improved coexistence performance with existing
2.4 GHz wireless technologies. Data rates are selectable from 2 Mbps to 125 kbps.
Due to the chip’s unique chirp pulse, adjustment of the antenna is not critical. This significantly simplifies the system’s installation and maintenance (“pick and place”).
A sophisticated MAC controller with CSMA/CA and TDMA support is included, as is
Forward Error Correction (FEC) and 128 bit hardware encryption. To minimize software and microcontroller requirements, nanoLOC also provides scrambling, automatic
address matching, and packet retransmission.

Integrated into the nanoLOC TRX Transceiver is the DDDL, a Digital Dispersive Delay
Line which is responsible for distinguishing between two possible incoming signals that
are generated by another nanoLOC chip. This received signal is either an Upchirp, a
Downchirp, or a folded pulse (an Upchirp and a Downchirp at the same time). All of
these signals have the same center frequency and the same bandwidth. The difference between an Upchirp and a Downchirp occurs only in the phase information of the
complex spectrum. This phase information is enough for the DDDL to compress a
pulse at one output port and expand it at the other (that is, to extend the incoming signal to the doubled duration). In this way the DDDL acts like a matched filter for one of
the possible transmitted pulses.
For more details see nanoLOC TRX Transceiver (NA5TR1) Datasheet available from
Nanotron.
This is a low power CMOS 8-bit microcontroller based on the AVR enhanced RISC
architecture with 64 Kb Flash, 4 Kb SRAM, and 2 Kb EEPROM. This microcontroller
drives the nanoLOC chip via the SPI interface and operates between 1.8 V and 5.5 V.
For more details, refer to the Atmel ATmega644V Datasheet available from Atmel.
At the RF interface of the nanoLOC chip, a differential impedance of 200 Ω exists
which is matched to the asymmetrical 50 Ω impedance of the antenna port by a 200 /
50 RF balun. Additional external components at the RF interface have a power and
noise matching function that allows a sharing of the antenna without an external RX/
TX – RF switch.
As well as this integrated antenna, an external 2.4 GHz antenna can also be connected to the module.
For an improved robustness against out of band inferences, an ISM band pass filter is
connected at the antenna port.
The 32.768 kHz Quartz is used for the Real Time Clock oscillator. The 16 MHz Quartz
is used by the ATmega microcontroller, while the 32 MHz Quartz works with the internal oscillator circuitry of the nanoLOC chip.
The nanoLOC AVR Module is programmable over JTAG or SPI interfaces. 36 peripheral module pins in total are provided, with 16 programmable digital IOs and 2 analog
inputs. The module also provides a pulse-width modulation (PWM) output, a microcontroller reset input, a Universal Synchronous RX/TX (USART) input/output, and a TX/
RX signal that enables an external PA.
