4 measurement limit (air discharge: ±15kV) of the
IEC61000-4-2 standard (electrostatic immunity
testing standard). In addition, implementing circuit
enhancements related to power lines and noise
intrusion pathways resulted in a 30% improvement in
noise resistance (verified via indirect discharge using
LAPIS Semiconductor’s reference board under specific
conditions).

Maxim’s Industrial IoT Reference Design
Speeds Development of Authenticated Data
Chains
Highly secure coprocessor supports Arduino® and
ARM® mbed™ platforms, assures easy prototyping
San Jose, CA – August 29, 2016 – Addressing the many
issues related to system security in Industrial Internet
of Things (IIoT) installations, the MAXREFDES143#
embedded security reference design from Maxim
Integrated Products, Inc. (NASDAQ: MXIM) provides
protection against counterfeit sensor data, guaranteeing
its authenticity and integrity along the entire data chain,
from transducer to the cloud.

Block diagram:
The rapid growth of IoT capabilities for industrial
applications comes with legitimate concerns about data
integrity, due to deliberate corruption of critical sensor
data anywhere between a source and the cloud. The
reference design’s sophisticated architecture and
components, Arduino-compatible hardware interface,
and ARM mbed libraries support simplifies development
of secure, uncorrupted, and authenticated sensor-to-
web data. It is ideal for analog sensor node and data
authentication in factory automation and industrial
processing applications.
The reference design’s two-stage hierarchical
architecture consists of a shield that communicates
to a web server, and a protected sensor node for data
acquisition and authentication. The shield includes a Wi-
Fi module; a DS2465 secure coprocessor for offloading
SHA-256 cryptographic computation; 1-Wire® and I²C
interfaces; user-interface LCD, LEDs, and pushbuttons;
along with alarm and logging functions. The sensor node
contains a DS28E15 secure authenticator, DS7505
temperature sensor, and MAX44009 light sensor.
Key Advantages
Fast Time-to-Market: Significantly reduces development
time using the provided hardware and source code to
implement an authenticated node solution and web
server interface
Ease-of-Use: Free evaluation web server provides an
immediate out-of-the box implementation for real-time
data collection and storage of sensor data
Secure: SHA-256 coprocessor offloads data
authentication task; securely stores node authentication
key; each node has a unique key
“The reference design is a powerful, much-needed tool
for addressing the genuine issues of data security and
authentication for Industrial IoT installations,” said Scott
Jones, Executive Director, Embedded Security, Maxim
Integrated. “The reference design combines the shield
and sensor node to offer a solution with a high level of
security and minimal development start-up effort, and
with low system-overhead burden.”
“Enabling robust security and data integrity is critical to
the continued adoption of IoT solutions,” said Michael
Horne, Vice President of Marketing and Sales, IoT
Business, ARM. “The MAXREFDES143# simplifies
testing with ARM mbed-compatible development boards,
allowing designers to rapidly develop resilient industrial
IoT platforms.”
Availability and Pricing
TheMAXREFDES143# IoTembedded security reference
design is available for $75 at Maxim’s website and select
franchised distributors. Hardware and firmware design
files are free and available online.
