Introduction
The SENARM01 serves as a building block for other products. This document
provides you with a description of its operation, basic specifications, safety
instructions, and regulatory information.
Theory of Operation
SENARM01 is a data acquisition, processing, and communication chip. It is
designed to acquire data from a variety of sensors, process that data, and
participate in a multihop wireless network. The device uses IEEE 802.15.4
standard for wireless communication.
Physical Characteristics
The module is packaged in an LCC68 form factor. The package pins bring out
analog input signals, digital input and output, and RF interface. The package is
physically shielded. The device buffers all input signals; it sources (or sinks) a
maximum of 25mA across all output pins.
Communication Characteristics
In normal operation, the OEM Module complies with this protocol to implement
various layers of the protocol stack:
•
Physical — 802.15.4 PHY - 250 kbps signal in 128 byte packets are encoded
using DSSS. The sequence of chips is modulated using O-QPSK and
transmitted in a 2.4 GHz band.

OEM Soldered Connections
SENARM01s can be soldered using standard reflow ovens (including lead-free
soldering) at a maximum temperature of 250 degrees C for 30 seconds. Only use
“No-Clean” solder paste. Do not clean or wash the printed circuit board (PCB)
after soldering. When you use “No-Clean” solder paste, cleaning is not necessary.
For the best connection to the PCB, the solder connection should fill the edge-
plated via hole almost to the top.

Safety and Regulatory Notices
FCC Compliance Statement
SENARM01 has been designed, constructed, and tested for compliance with FCC
Rules that regulate intentional and unintentional radiators.
CAUTION: The user is not permitted to make any modifications to this equipment
without express approval from Sentilla Inc. Doing so will void the user’s authority
to operate this equipment.
This equipment has been tested and found to comply 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 devices must accept any interference received, including interference that
may cause undesired operation.
These limits are designed to provide reasonable protection 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 in accordance with the instructions, may cause harmful interference to
radio communications.
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 own expense.
However, there is no guarantee that interference will not occur in a particular
installation.
