MeshConnect™ EM357 Module
DESCRIPTION
CEL’s MeshConnect™ EM357 Module combines high perfor-
mance RF solution with the market's premier ZigBee stack.
The addition of on board memory enables Over-The-Air (OTA)
programming without the need for additional in system memory.
The integrated power amplier maximizes range and perfor-
mance. The small module footprint makes it suitable for a wide
range of ZigBee applications. The MeshConnect EM357 mod-
ule is certied and qualied enabling customers to accelerate
time to market by greatly reducing the design and certication
phases of development.
CEL’s MeshConnect™ EM357 module (ZICM357P2) is based
on the Ember EM357 Zigbee compliant SOC IC. The IC is a
single-chip solution, compliant with ZigBee specications and
IEEE 802.15.4, a complete wireless solution for all ZigBee
applications. The IC consists of an RF transceiver with the
baseband modem, a hardwired MAC and an embedded 32-bit
ARM® Cortex™-M3 microcontroller with internal RAM (12kB)
and Flash (192kB) memory. The device provides numerous
general-purpose I/O pins and peripheral functions such as
timers and UARTs.
The MeshConnect EM357 module adds a power amplier (PA)
to increase range, provide more reliable transmission, and re-
duce the number of nodes in a network. It is useful for open
outdoor applications where the nodes are physically far apart
or for indoor areas where the nodes have to operate in a noisy
RF environment. The Module’s outstanding 120dB link budget
ensures high quality connections even in such harsh environ-
ments.
The MeshConnect EM357 module also integrates an optional
1MB Flash memory for Over-The-Air program updates, making
this device ready for Smart Energy Applications.

TRANSCEIVER IC
The MeshConnect EM357 module uses the Ember EM357 transceiver IC. This IC incorporates the RF transceiver with the
baseband modem, a hardwired MAC, and an embedded ARM® Cortex™-M3 microcontroller, offering an excellent low cost
high performance solution for all IEEE 802.15.4 / ZigBee applications.
For more information about the Ember EM357 IC, visit http://www.ember.com
ADDITIONALFLASHMEMORY
The MeshConnect EM357 modules (ZICM357P2-1 and ZICM357P2-2C) incorporates an optional additional 1MB external
Flash memory for Over-The-Air program updates. The Flash memory communicates over the EM357’s second serial con-
troller using SPI. The ash memory is wired to the following castellation pins:
PA0 - SC2MOSI EM357 Module pin number 3
PA1 - SC2MISO EM357 Module pin number 4
PA2 - SC2SCLK EM357 Module pin number 5
PA3 - SC2nSSEL EM357 Module pin number 6
WP - Flash memory Write Protect line (has internal pull-up resistor, but not connected to the EM357) EM357 Module pin number 2
The instruction set for the Flash memory is similar to the Micron M25P80 (ZICM357P2-1) and Micron M25PE80
(ZICM357P2-2C). Note that in order to achieve the specied sleep current for the module, it is necessary to send a Deep
Power-Down command to the Flash memory.
See http://www.micron.com for more information on the instruction set.
ANTENNA
CEL’s MeshConnect modules include an integrated Printed Circuit Board (PCB) trace antenna. An optional U.FL connector
can be specied, providing connection to a 50-ohm external antenna of the user’s choice. However use of an external an-
tenna is not covered by the module's certication. See Ordering Information on page 1.
For optimum antenna performance, the MeshConnect modules should be mounted with the PCB trace antenna
overhanging the edge of the host board. To further improve performance, a ground plane may be placed on the host board
under the module, up to the antenna. The installation of an uninterrupted ground plane on a layer directly beneath the
module will also allow you to run traces under this layer. CEL can provide assistance with your PCB layout.
The PCB antenna employs an Inverted F-Antenna topology that is compact and highly efcient. To maximize range, an
adequate ground plane must be provided on the host PCB. Correctly positioned, the ground plane on the host PCB will
contribute signicantly to the antenna performance (it should not be directly under the Inverted F-Antenna). The position of
the module on the host board and overall design of the product enclosure contribute to antenna performance. Poor design
affects radiation patterns and can result in reection, diffraction, and/or scattering of the transmitted signal.
Here are some design guidelines to help ensure antenna performance:
• Never place the ground plane or route copper traces directly underneath the antenna portion of the module.
• Never place the antenna close to metallic objects.
• In the overall design, ensure that wiring and other components are not placed near the antenna.
• Do not place the antenna in a metallic or metalized plastic enclosure.
• Keep plastic enclosures 1cm or more from the antenna in any direction.
POWERAMPLIFIER
The MeshConnect EM357 Module includes a Power Amplier (PA). This PA delivers high efciency, high gain, and high
output power (Pout = +20.0 dBm TYP) to provide an extended range and reliable transmission for fewer nodes in a
network.
The PA is connected to the alternate EM357 IC TX output, so EM357 TX power modes 2 or 3 must be used to achieve the
specied output power.
SOFTWARE/FIRMWARE
The MeshConnect EM357 Module is an ideal platform for the EmberZNet PRO, the industry’s most deployed and eld
proven ZigBee compliant stack supporting the ZigBee PRO feature Set. EmberZNET PRO is a complete ZigBee protocol
software package containing all the elements required for mesh networking applications. For more information regarding
the software development for this IC, visit http://www.ember.com
CEL provides reference software that runs multiple functions and executes various commands. The rmware allows the
execution of IEEE 802.15.4 communication, validation and manufacturing tests. For example, users can setup a simple
ZigBee Point-to-Point network to perform Range and Packet Error Rate (PER) tests. The software can also place the mod-
ule in various operating modes, which allows for setting and/or testing various parameters.

Pb-Free Solder Paste
Use of “No Clean” soldering paste is strongly recommended, as it does not require cleaning after the soldering process.
Note: The quality of solder joints on the castellations (‘half vias’) where they contact the host board should meet the appropriate IPC Speci-
cation. See the latest IPC-A-610 Acceptability of Electronic Assemblies, Castellated Terminations section.
Cleaning
In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed
with any cleaning process.
• Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and
the module. The combination of soldering ux residuals and encapsulated water could lead to short circuits between
neighboring pads. Water could also damage any stickers or labels.
• Cleaning with alcohol or a similar organic solvent will likely ood soldering ux residuals into the two housings, which
is not accessible for post-washing inspection. The solvent could also damage any stickers or labels.
• Ultrasonic cleaning could damage the module permanently.
The best approach is to consider using a “no clean” solder paste and eliminate the post-soldering cleaning step.
Optical Inspection
After soldering the Module to the host board, consider optical inspection to check the following:
• Proper alignment and centering of the module over the pads.
• Proper solder joints on all pads.
• Excessive solder or contacts to neighboring pads, or vias.
RepeatingReowSoldering
Only a single reow soldering process is encouraged for host boards.
WaveSoldering
If a wave soldering process is required on the host boards due to the presence of leaded components, only a single wave
soldering process is encouraged.

PROCESSING (Continued)
AGENCYCERTIFICATIONS
HandSoldering
Hand soldering is possible. When using a soldering iron, follow IPC recommendations (reference document IPC-7711)
Rework
The MeshConnect Module can be unsoldered from the host board. Use of a hot air rework tool should be programmable
and the solder joint and module should not exceed the maximum peak reow temperature of 250 ºC.
Caution If temperature ramps exceed the reow temperature prole, module and component damage may occur due to
thermal shock. Avoid overheating.
WarningNever attempt a rework on the module itself, e.g. replacing individual components. Such actions will
terminate warranty coverage.
Additional Grounding
Attempts to improve module or system grounding by soldering braids, wires, or cables onto the module RF shield cover is
done at the customer's own risk. The numerous ground pins at the module perimeter should be sufcient for optimum
immunity to external RF interference.

QUALITY
Software Compliance
The ZICM357P2 requires software restrictions to meet agency certication requirements. These restrictions have been
implemented in the sample application included with the software development kit.
If a customer is not starting with CEL's software development kit, they must implement these output power restrictions to
use the ZICM357P2 FCC, IC or ETSI certication:
Certication RFChannel Valid TX Power Steps
FCC/IC
11 - 23 -43 to 8
24 -43 to -9
25 -43 to -20
26 Disabled
ETSI 11 - 26 -43 to -14
Note: The software development kit does not implement the ETSI restrictions.
CEL modules offer the highest quality at competitive prices. Our modules are manufactured in compliance with the IPC-A-610
specication, Class II. Our modules go through JESD22 qualication processes which includes high temperature operating life
tests, mechanical shock, temperature cycling, humidity and reow testing. CEL conducts RF and DC factory testing on 100%
of all production parts.
CEL builds the quality into our products, giving our customers condence when integrating our products into their systems.
