Arm Demonstrates New IoT Test Chip and Board for Highly Efficient, Secure IoT Designs



Reading Time: 4 minutes

Built on Samsung Foundry 28nm FD-SOI process technology, the Musca-S1
test chip demonstrates a new choice in SoC design for IoT solutions

News Highlights

  • Arm debuts eMRAM-enabled test chip on Samsung Foundry process
    technology, including capability to run Mbed OS and Arm Pelion IoT
  • The Musca-S1 test chip demonstrates capabilities of FD-SOI body
    biasing and eMRAM technology to be used in SoC designs for highly
    energy-efficient IoT devices
  • Test chip and development board are expected to be available for
    evaluation to IoT device designers by Q4 2019

SAN JOSE, Calif.–(BUSINESS WIRE)–Today at the Samsung Foundry Forum, Arm, in collaboration with Samsung
Foundry, Cadence, and Sondrel, demonstrated the first 28nm
fully-depleted silicon-on-insulator (FD-SOI) embedded MagnetoResistive
Random Access Memory (eMRAM) IoT test chip and development board. The
Musca-S1 is designed to offer more choice to IoT designers in their
system-on-chip (SoC) development journey. Designers can now easily
implement more secure, holistic IoT solutions, enabling them to focus
more on core product differentiation and accelerating time-to-market.

“The promise of a world transformed by a trillion connected devices is
not far in the future, but for IoT devices to scale we must continue to
put a range of technology options in front of designers to test and
evaluate,” said Gus Yeung, VP, GM and Fellow, Physical Design Group,
Arm. “This collaboration has yielded a true end-to-end solution that
ensures IoT designers can prototype their product designs from
device-to-data security.”

to previous Musca solutions
, the Musca-S1 test chip board now
includes testing and evaluation of new eMRAM technology for reliable,
low-power and secure device development through secure memory
implementation. eMRAM technology offers advantages over traditional
embedded flash (eFlash) memory technology, as it can easily scale below
40nm process technology, giving SoC designers more flexibility to scale
their memory needs based on the memory and power requirements of various


Musca-S1 test chip demonstrates a combination of on-chip power control,
Samsung Foundry’s Reverse Body Biasing (RBB) and eMRAM non-volatile
memory power shutdown, allowing for testing and evaluation of new
classes of highly energy-efficient, controlled IoT devices. And for the
first time on Samsung Foundry silicon, designers will have the
opportunity to run Arm® Mbed™OS as well as
test device and data management capabilities using the Arm Pelion™
IoT platform.

By combining Arm IP and software solutions on a single board, IoT
designers can test and evaluate Arm’s end-to-end secure IoT solution,
showcasing highly energy-efficient and secure IoT at scale.
Additionally, the Musca-S1 test chip board can further reduce costs and
time-to-market by giving designers the flexibility to repurpose the
reference design for future products.

Availability and more information

The Musca-S1 test chip and development board is on display at Samsung
Foundry Forum North America in San Jose, CA as part of an air sensor IoT
application demo, featuring the device and data management capabilities
of the Arm Pelion IoT platform.

The Musca-S1 will be available in limited quantities in Q3 2019, and is
targeted for loan to customers in Q4 2019. Contact Arm for more
information on the Musca-S1 test chip and development board.

“This collaboration with our SAFE Partners Arm, Cadence and Sondrel
brings the Arm Musca test chip and development board to Samsung Foundry
silicon for the first time. The combination of Musca-S1 and working
28FD-SOI silicon reassures IoT designers they can achieve faster
development, deploy body biasing and integrate eMRAM technology in their
next-generation IoT devices for enhanced energy efficiency and IoT

KT Moore, vice president, product management in the Digital & Signoff
Group, Cadence

“The Musca-S1, the industry’s first silicon-proven 28nm FD-SOI eMRAM and
Cadence® IP-based IoT SoC, was implemented using the Cadence digital and
signoff full-flow solution, which supports back biasing from synthesis
through signoff, including physical verification and DFM signoff. In
addition, the Musca-S1 was verified using the Cadence Verification
Suite, with protocol compliance verified with Cadence VIP and memory
models. Through our collaboration with Arm, Samsung and Sondrel, we’re
enabling mutual customers to confidently
create power-efficient MRAM-enabled IoT edge-devices with built-in
security and connectivity capabilities, as well as further accelerating
innovation in emerging application areas.”

Graham Curren, CEO, Sondrel


“Musca-S1 is not just a design solution to secure internet connected
devices and manage them at scale, but a simple and safe route to market
based on a collaboration between semiconductor industry leaders. It
addresses products from the simplest to the most intelligent edge node
devices, and brings together the best combination of tools, technology,
processes and people to set a new standard for robust IoT device design.”
