1.12 Mounting Details
The RN4677 physical dimensions are shown in
Figure 1-6, recommended host PCB footprint in
Figure 1-7, and mounting suggestion in Figure 1-8. No
top copper layer must be near the test pin area as
shown in Figure 1-7. When laying out the host PCB, the
areas under the antenna must not contain any top,
inner layer, or bottom copper as shown in Figure 1-8. A
low-impedance ground plane ensures best radio
performance (best range; lowest noise). Figure 1-8
also shows a minimum ground plane area to the left
and right of the module for best antenna performance.
The ground plane can be extended beyond the
minimum recommended, see Figure 1-7, as required
for host PCB EMC noise reduction. For best range
performance, keep all external metal away from the
ceramic chip antenna at least 31 mm.
1.13 Soldering Recommendations
The RN4677 wireless module was assembled using
standard lead-free reflow profile IPC/JEDEC J-STD-
020.
The module can be soldered to the host PCB using
standard leaded and lead-free solder reflow profiles.
To avoid damaging the module, the following
recommendations are given:
• Microchip Technology Application Note “AN233
Solder Reflow Recommendation” (DS00233)
provides solder reflow recommendations
•Do not exceed peak temperature (TP) of 250°C
Refer to the solder paste data sheet for specific
reflow profile recommendations
• Use no-clean flux solder paste
•Do not wash as moisture can be trapped under
the shield
• Use only one flow. If the PCB requires multiple
flows, apply the module on the final flow.

The RN4677 module has been certified for use in
Canada under Industry Canada (IC) Radio Standards
Specification (RSS) RSS-210 and RSS-Gen. Modular
approval permits the installation of a module in a host
device without the need to recertify the device.
3.2.1 LABELING AND USER
INFORMATION REQUIREMENTS
Labeling Requirements for the Host Device (from
Section 3.2.1, RSS-Gen, Issue 3, December 2010):
The host device shall be properly labeled to identify the
module within the host device.
The Industry Canada certification label of a module
shall be clearly visible at all times when installed in the
host device, otherwise the host device must be labeled
to display the Industry Canada certification number of
the module, preceded by the words “Contains
transmitter module”, or the word “Contains”, or similar
wording expressing the same meaning, as follows:
User Manual Notice for License-Exempt Radio
Apparatus (from Section 7.1.3 RSS-Gen, Issue 3,
December 2010): User manuals for license-exempt
radio apparatus shall contain the following or
equivalent notice in a conspicuous location in the user
manual or alternatively on the device or both:
Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010): User manuals for
transmitters shall display the following notice in a
conspicuous location:
The above notice may be affixed to the device instead
of displayed in the user manual.
Contains transmitter module
IC: 12246A-BM77SPPSYC2.
This device complies with Industry Canada license-
exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not
cause interference, and (2) this device must accept
any interference, including interference that may
cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Indus-
trie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux con-
ditions suivantes: (1) l'appareil ne doit pas produire
de brouillage, et (2) l'utilisateur de l'appareil doit
accepter tout brouillage radioélectrique subi, même si
le brouillage est susceptible d'en compromettre le
fonctionnement.
Under Industry Canada regulations, this radio trans-
mitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the trans-
mitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotrop-
ically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
Conformément à la réglementation d'Industrie Can-
ada, le présent émetteur radio peut fonctionner avec
une antenne d'un type et d'un gain maximal (ou
inférieur) approuvé pour l'émetteur par Industrie Can-
ada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il
faut choisir le type d'antenne et son gain de sorte que
la puissance isotrope rayonnée équivalente (p.i.r.e.)
ne dépasse pas l'intensité nécessaire à l'établisse-
ment d'une communication satisfaisante.

User manuals for transmitters equipped with
detachable antennas shall also contain the following
notice in a conspicuous location:
Immediately following the above notice, the
manufacturer shall provide a list of all antenna types
approved for use with the transmitter, indicating the
maximum permissible antenna gain (in dBi) and
required impedance for each.
3.2.2 RF EXPOSURE
All transmitters regulated by IC must comply with RF
exposure requirements listed in RSS-102 - Radio
Frequency (RF) Exposure Compliance of
Radiocommunication Apparatus (All Frequency
Bands).
3.2.3 APPROVED EXTERNAL ANTENNA
TYPES
Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010):
The RN4677U module can only be sold or operated
with antennas with which it was approved. Transmitter
may be approved with multiple antenna types. An
antenna type comprises antennas having similar in-
band and out-of-band radiation patterns. Testing shall
be performed using the highest gain antenna of each
combination of transmitter and antenna type for which
approval is being sought, with the transmitter output
power set at the maximum level. Any antenna of the
same type having equal or lesser gain as an antenna
that had been successfully tested with the transmitter,
will also be considered approved with the transmitter,
and may be used and marketed with the transmitter.
When a measurement at the antenna connector is
used to determine RF output power, the effective gain
of the device's antenna shall be stated, based on
measurement or on data from the antenna
manufacturer. For transmitters of output power greater
than 10 milliwatts, the total antenna gain shall be added
to the measured RF output power to demonstrate
compliance to the specified radiated power limits.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
